If you’ve ever stood in a yarn shop holding two different balls of DK cotton wondering which one to pick — this article is for you.
After making dozens of baby shoes, bonnets, and blankets, we’ve worked with a lot of different yarns. Some have been wonderful. Some have unravelled after two washes. Some looked beautiful in the skein and turned out far too stiff for a baby’s foot once crocheted up.
This is what we actually use at Bloom Bonnet, and why.
What Matters Most When Choosing Yarn For Baby Items
Before we get into specific yarns, here are the four things we check every time.
Softness — test it on your cheek, not your hand
Your hands are callused from crocheting. Baby skin isn’t. The standard test is to press the yarn against your inner wrist or cheek — if it feels even slightly scratchy there, it’s not going near a baby. We’ve rejected several otherwise good yarns this way.
Washability — parents need this to be easy
Handmade baby gifts that can’t go in the washing machine are a stress for parents. We only ever use yarns that are confirmed machine washable at 30°C or above. Items like baby shoes get washed constantly — they need to come out of the machine looking the same as when they went in.
Stitch definition — especially important for shoes
For structured items like baby shoes, you need a yarn where you can clearly see each stitch. This matters both while you’re crocheting (so you don’t miss a stitch) and in the finished item (so it looks neat and intentional). Cotton wins here. Bamboo blends and soft acrylics can blur the stitches slightly.
Durability after repeated washing
We wash our test items multiple times before publishing a pattern. A yarn that pills badly, loses its shape, or fades significantly after five washes doesn’t make the cut — no matter how nice it feels fresh from the ball.
The Yarns We Actually Recommend
100% Cotton DK — Our Go-To For Almost Everything
Cotton is what we reach for first. It’s the yarn used in our Free Crochet Baby Shoes Pattern — every step photo in that tutorial was made with a soft DK cotton, and you can see how cleanly the stitches show up.
What we’ve found from actually using it:
- Stitch definition is noticeably better than bamboo blends — cleaner edges, easier to count rows
- Holds its shape perfectly after machine washing. We’ve washed our test shoes around 8 times and they still look good
- It’s not stretchy, which feels slightly unforgiving when you’re learning, but means the finished shoe keeps its structure
- The tension can feel a little stiffer than acrylic — if you crochet tightly, go up half a hook size
Our shoes used approximately 38g per pair with DK cotton on a 4.0mm hook.
What we use: Lion Brand 24/7 Cotton in DK. It’s widely available, consistent between dye lots, and photographs beautifully — which matters when you’re taking step-by-step photos.
Best for: Baby shoes, booties, hats, bonnets — anything where the item needs to hold its shape.
Bamboo-Cotton Blend — The Softest for Blankets
We tried bamboo-cotton blends for a small blanket project and the softness was genuinely impressive — noticeably silkier than straight cotton. But it behaved very differently on the hook.
What we noticed:
- The yarn splits more easily when working into tight stitches. You’ll need to slow down and be deliberate with your hook placement
- Stitch definition is softer — beautiful for blankets, but we wouldn’t use it for shoes where you need crisp edges
- The drape is lovely. Blankets made in bamboo-cotton feel fluid and light rather than structured
- It’s more expensive per gram than cotton, so factor that in for larger projects
Best for: Baby blankets and wraps where softness and drape matter more than structure.
Soft Acrylic — Better Than You’d Think, If You Choose Carefully
Acrylic gets a bad reputation in handmade communities, and some of it deserves it. Budget acrylic can feel plasticky and is definitely not suitable for baby skin.
But a quality soft acrylic is a different thing entirely. We’ve used Paintbox Simply DK for hats and it’s genuinely soft to the cheek test.
What makes it useful:
- Machine washable and often tumble-dryer safe — very practical for busy parents
- Consistent tension across the skein, which makes it forgiving for beginners
- Wide colour range, including very pale pastels that are hard to find in cotton
- More elastic than cotton, which some people find easier to work with
The honest downside: it’s less breathable than natural fibres, and you can sometimes feel the difference in a summer hat. For cooler months or blankets, this matters less.
Best for: Baby blankets, winter hats, projects where colour choice matters more than breathability.
Superwash Merino Wool — For Winter Items, Older Babies
We haven’t used merino wool for our published patterns yet, but we’ve tested it. Superwash merino is genuinely impressive — incredibly soft, temperature-regulating, and it doesn’t felt in the wash as long as you use the superwash variety.
The reason we’re cautious about recommending it for newborns is simple: wool contains lanolin, a natural oil that some people and babies are sensitive to. It’s not common, but it does happen, and for a gift item where you don’t know the baby’s skin, it’s a risk we’d rather avoid.
For babies over three months where you know there’s no sensitivity, superwash merino makes beautiful winter hats and blankets.
Best for: Winter hats and blankets for older babies (3+ months) where you know the recipient.
Yarn Weight Guide For Baby Projects
This is what we actually use — not just what the pattern calls for, but what we’ve found works best in practice.
| Item | Weight | Hook | Notes |
|---|---|---|---|
| Baby shoes / booties | DK (size 3) | 4.0 mm | Cotton gives best shape retention |
| Baby hats | DK (size 3) | 4.0–4.5 mm | Acrylic works well here |
| Baby bonnets | DK (size 3) | 3.5–4.0 mm | Cotton for structure |
| Baby blankets | DK–Worsted (3–4) | 4.5–5.5 mm | Bamboo-cotton or soft acrylic |
| Newborn items | Sport–DK (2–3) | 3.0–4.0 mm | Stick to cotton for the youngest |
For reference, the baby shoes in our pattern used exactly 38g of DK cotton and took roughly 55 minutes per pair at a comfortable pace.
Yarns We’d Avoid For Baby Projects
These are things we’ve either tried and abandoned, or specifically checked and decided against:
- Budget scratchy acrylic — the cheek test tells you immediately. Don’t talk yourself into it
- Novelty yarns (eyelash, fuzzy, boucle) — the loose fibres are a real concern for very young babies
- Untreated wool — will felt in the wash. We made this mistake once with a test swatch. Never again
- Heavily dyed dark colours for newborns — we tend to stick to undyed or pale colours for the youngest babies just to minimise any dye irritation risk. Once babies are a few months old this matters much less
What To Look For On The Label
If you’re buying yarn online and can’t do the cheek test in person, check the label for:
- Machine washable at 30°C or above — non-negotiable for gifted items
- OEKO-TEX Standard 100 — independently tested for harmful substances. Not every good yarn has this, but it’s a strong signal when it does
- DK / size 3 for most baby patterns
- 100% cotton or bamboo-cotton blend for the most skin-safe choice
Frequently Asked Questions
What yarn is best for crochet baby shoes? DK weight 100% cotton. We use it for all our shoe patterns — it gives clear stitch definition, holds its shape after washing, and is easy to work with. Our baby shoes used 38g per pair on a 4.0mm hook.
Can I use acrylic yarn for baby items? Yes, if it’s genuinely soft. Run it across your cheek before buying. Quality soft acrylics like Paintbox Simply DK work well for hats and blankets. We’d avoid acrylic for shoes specifically, as cotton holds structure better.
Is cotton or acrylic better for baby blankets? Both work. We reach for bamboo-cotton when softness is the priority, and soft acrylic when we want a specific colour that doesn’t come in cotton. For the most breathable option, cotton wins.
Can I use wool for baby items? Superwash merino works well for older babies, but we’d be cautious gifting wool items for newborns without knowing the baby’s skin. The lanolin in wool can occasionally cause sensitivity. For the safest choice for very young babies, stick to cotton.
How much yarn do I need for baby shoes? Around 38–50g for DK weight, depending on the size and your tension. Our pattern uses approximately 38g per pair. Buy one 50g ball and you’ll have enough with a little to spare.
