Design by Alli Crafts.
This pretty baby hat pattern is given in one size to fit a 3-month-old, but links to other sizes can be found on the pattern page. The open stitch design makes this perfect for warmer weather. For the winter months, you could easily line the inside with a cozy fabric.
It features a pretty rose, but any flower applique will look just as nice. And for a little boy, you could add a little animal applique if you like.
You will need a worsted weight yarn and an H crochet hook.
