The short answer
Use mercerized cotton. Size 10 crochet thread is the best overall choice for flat ornaments - snowflakes, stars, lace - because it is the only material here that blocks rigid enough to hang flat and takes stiffening properly. For stuffed amigurumi ornaments use a mercerized worsted cotton such as Lion Brand 24/7 Cotton, which gives tight stitch definition and hides the stuffing. Plain kitchen cotton is the budget answer for a batch of twenty. Avoid anything fuzzy: ornaments are inspected from a foot away, and chenille, mohair and brushed acrylic all turn a detailed shape into a lump.

Aunt Lydia's Classic Crochet Thread Size 10
Aunt Lydia's · Best for snowflakes, stars, lace and anything that must hold a flat shape
The size 10 mercerized cotton thread almost every doily, edging and thread-crochet pattern in print assumes.
- Fiber
- 100% mercerized cotton, 3-ply
- Weight
- Crochet thread weight 10
- Yardage
- White, ecru and natural 400yd; solids 350yd; shaded colors 300yd
- Also made as
- Large and jumbo put-ups of the same thread
Who it suits
Anyone making snowflakes or openwork ornaments, and anyone who wants the heirloom-lace look.
Why it is here
100% mercerized cotton thread, size 10. Two things make it right for this. The mercerization gives it a hard, smooth, slightly glossy surface that catches tree lights, and the fineness means a 4-inch snowflake has enough stitches to actually be a snowflake rather than a blob. Thread also takes stiffening - starch, sugar solution or a commercial stiffener - better than any yarn, which is how a flat ornament stays flat.
What you give up
It is slow. A thread snowflake on a 1.65mm steel hook is an evening per ornament, not a batch. It also needs [steel hooks](/crochet-hooks/best-steel-crochet-hooks), which most people do not own, and it is hard on the hands and eyes.

Lion Brand 24/7 Cotton
Lion Brand · Best for stuffed shapes - gnomes, baubles, little animals
Mercerized cotton with a sheen and a stiff hand. Stitch definition is the best on this page, which is why amigurumi people keep buying it.
- Fiber
- 100% mercerized cotton
- Weight
- Worsted
- Skein
- 3.5oz / 100g, 186yd / 170m
- Gauge
- 19 sts x 26 rows on 5mm (US 8)
- Hook
- 5.5mm (US I/9), 16 sc x 18 rows
- Care
- Machine wash, water not above 105F; medium heat dryer
Who it suits
Anyone making stuffed ornaments rather than flat ones, and anyone who wants the stitches to read clearly.
Why it is here
100% mercerized cotton, worsted weight, machine wash and tumble dry. Amigurumi lives or dies on stitch definition and on the fabric being dense enough to hide the stuffing, and mercerized cotton is the standard answer to both. The sheen also photographs and reads well under tree lights, where a matte acrylic goes flat.
What you give up
Cotton has no give, so working at the tight gauge amigurumi needs is hard on the hands. It is also heavier than acrylic, which matters a little on a branch.

Lily Sugar'n Cream
Lily · Best for a batch of twenty for the school fair or the office tree
Unmercerized cotton in a small 2.5oz ball. Absorbent, hard-wearing, and the reason every dishcloth pattern ever written specifies it.
- Fiber
- 100% cotton
- Weight
- 4 Medium / worsted
- Ball
- 2.5oz / 71g, 120yd / 109m
- Gauge
- 20 sts x 26 rows on 4.5mm (US 7)
- Hook
- 5mm (US H/8), 13 sc x 14 rows
- Care
- Machine wash not above 86F delicate, tumble dry low
Who it suits
Anyone making ornaments at volume, and anyone making them with children.
Why it is here
100% cotton, worsted weight. It is the default kitchen-cotton and that is exactly why it works here - it holds a stitch, it is stiff enough for small shapes without stiffening, it comes in red, green and white, and the cost per ornament is pennies.
What you give up
Unmercerized cotton is matte and a little fuzzy, so it does not catch the light the way the mercerized options do, and the fuzz gets worse with handling. It also splits more than mercerized cotton when you are working tightly.

Paintbox Yarns Cotton DK
Paintbox Yarns · Best for ornaments that need a specific shade, in small quantities
Plain 100% cotton at DK weight in a 50g ball - the cheapest way to buy a known cotton gauge in a lot of colors.
- Fiber
- 100% cotton
- Weight
- DK / light worsted
- Ball
- 50g (1.76oz), 137yd (125m)
- Needle
- US 6 (4mm)
- Gauge
- 22 sts x 30 rows to 4in
- Hook
- F (4.00mm)
- Care
- Machine wash 40C/105F, no bleach, do not tumble dry, iron medium
Who it suits
Anyone making multicolor ornaments, and anyone who needs one small amount of an exact color.
Why it is here
100% cotton, DK weight, 50g at 137yd, hook F (4.00mm). The ball size is the actual argument: ornaments use tiny amounts, and a 50g ball lets you buy a palette rather than committing to full skeins you will never finish. DK is also a half-step finer than worsted, which gives a slightly crisper small shape.
What you give up
Do not tumble dry it - the care label says machine wash but not tumble dry, unlike the mercerized options. At DK weight your ornaments also come out a little smaller than a worsted pattern expects.

Bernat Blanket
Bernat · Best for blankets
Polyester chenille at 108 yards to a 150g ball. Fast, warm, machine washable, and it will shed and worm if the tension is loose.
- Fiber
- 100% polyester (chenille)
- Weight
- 6 Super Bulky
- Ball
- 5.3oz / 150g, 108yd / 98m
- Gauge
- 8 sts x 13 rows on 8mm (US 11)
- Hook
- 8mm (US L/11), 7 sc x 8 rows
- Care
- Machine wash delicate, tumble dry gentle
Who it suits
Nobody, for ornaments.
Why it is here
100% polyester chenille at super bulky. Ornaments are judged on stitch definition at close range and chenille's pile obliterates it - the whole surface reads as fuzz. At super bulky weight a small ornament is also only a handful of stitches, so there is no shape to make.
What you give up
None here. If you want a plush holiday object, make a chunky throw instead.

Why ornaments invert the usual rules
Everything else in this hub is chosen for softness, drape or warmth. An ornament wants none of those. It is a small, rigid, decorative object that hangs at eye level and gets looked at closely.
- Stitch definition is the whole product. At this size the stitches are the design. Anything with a halo erases it.
- Stiffness is a feature. A flat ornament that flops is a failure. Cotton is stiff; wool and acrylic are not.
- Small yardage, many colors. A whole ornament is often under 20 yards. Buy small balls in many shades rather than big skeins in a few.
- It has to survive storage. Eleven months in a box with other ornaments. Cotton does not attract moths and does not crush permanently.
- Light matters. Mercerized cotton has a sheen that catches tree lights. Matte fibers go dead next to a bulb.
Flat ornaments versus stuffed ones
These are two different projects with two different material answers, and most disappointment comes from using the wrong one.
| Ornament type | Material | Hook | Needs stiffening? |
|---|---|---|---|
| Snowflake, star, flat lace | Size 10 thread | Steel, 1.5-1.8mm | Yes - that is the point |
| Flat motif in yarn | DK or worsted cotton | 3.5-4mm | Usually |
| Amigurumi bauble, gnome, animal | Worsted mercerized cotton | 2.5-3.5mm, tight | No - stuffing holds it |
| Granny-square ornament | DK cotton | 3.5-4mm | Light blocking only |
| Covered bauble (crochet over a ball) | DK cotton or thread | 3-4mm | No - the ball holds it |
| Chunky rustic ornament | Worsted wool | 5mm | Blocks, does not stiffen |
Stiffening, honestly
A flat thread ornament has to be stiffened or it will curl. There are three common methods and they are not equivalent.
- Commercial fabric stiffener. The most predictable and the most expensive. Dries clear and hard, does not yellow, and is the right choice for anything you intend to keep.
- Sugar or starch solution. Cheap and traditional. It works, and it is hygroscopic - in a humid house the ornament softens again, and sugar can attract insects in storage.
- White glue thinned with water. Cheap and very rigid. It can yellow over years, which matters on a white snowflake and does not on a red one.
- Block it while it dries, always. Pin the wet ornament to a flat surface over a towel, to shape, and leave it until it is bone dry. The pinning does as much work as the stiffener.
- Do not stiffen amigurumi. Stuffed ornaments hold their own shape; stiffener just makes them crunchy.
A batch-production note
If you are making twenty of these for a fair or a tree, the limiting factor is not yarn cost - it is your hands. Thread ornaments on a steel hook are genuinely tiring, and twenty of them is a long month.
Work in worsted cotton at a 3.5mm hook instead and you will finish the batch. The ornaments are chunkier and less delicate, and they are finished. If you do go the thread route, best steel crochet hooks covers the tools and best crochet hook for arthritis is worth reading first if your hands already complain.
Questions people actually ask
What is the best yarn for crochet Christmas ornaments?
Mercerized cotton. Size 10 crochet thread for flat ornaments like snowflakes, because it blocks rigid and takes stiffening; a mercerized worsted cotton such as Lion Brand 24/7 Cotton for stuffed amigurumi ornaments, because it gives tight stitch definition and hides the stuffing.
Can you use regular yarn for Christmas ornaments?
Yes, as long as it is smooth. Worsted or DK cotton works well and is far faster than thread. Avoid anything with a halo - chenille, mohair and brushed acrylic all obliterate the stitch definition that makes a small ornament read as a design rather than a lump.
How do you stiffen a crochet ornament?
Commercial fabric stiffener is the most predictable and does not yellow. Sugar or starch solution is the cheap traditional method but softens again in humidity. Whatever you use, pin the wet ornament flat to shape and let it dry completely - the pinning matters as much as the stiffener.
What size thread for crochet snowflakes?
Size 10 is the standard and what most patterns assume. Remember the numbering runs backwards: size 10 is the thickest commonly sold and size 20 and above get finer. Size 10 pairs with a steel hook around 1.5 to 1.8mm.
How much yarn does one ornament take?
Usually under 20 yards, often under 10. That changes how you buy: get small balls in many colors rather than big skeins in a few, which is why a 50g DK cotton is a better purchase here than a 200g worsted skein.
Will cotton ornaments survive storage?
Yes - cotton does not attract moths and does not crush permanently the way a pile fabric does. Store them in a rigid box rather than a bag so flat ornaments are not bent, and make sure stiffened ones are fully dry before they go away.
