The Happy Hearts Sweater is a sweet and timeless child crochet sweater pattern designed for babies and children from 0–6 months through to 10 years.

Worked completely seamlessly from the top down, the sweater uses the overlay mosaic crochet technique to create beautiful heart motifs around the yoke. The hearts look wonderfully detailed but are created using simple US single crochet and double crochet stitches, making this a lovely introduction to mosaic crochet for adventurous beginners.

This heart crochet sweater pattern includes both fully written instructions and complete mosaic charts for the yoke, so you can choose whichever format you prefer to follow.

Once the heart yoke is complete, there are plenty of ways to make the sweater your own.

You can:
Adjust the body length to suit your child.
Choose from sleeveless, short, three-quarter or long sleeves (with or without cuffs).
Add a neckband or leave it open for a more relaxed finish.
Play with colour combinations to make those Happy Hearts completely your own.

The seamless, top-down construction also makes it easy to adjust the fit and length as you crochet — particularly handy when little people insist on growing quite so quickly.
A wonderful crochet garment project for adventurous beginners and beyond, allowing the mosaic crochet heart detail to do all the hard work while you crochet with simple stitches.
