Rockin’ Romper Free Crochet Pattern

If you’ve got little ones to dress this summer, you’re going to love this little Rockin’ Romper crochet pattern. This is THE most adorable infant romper and so quick to make too!

Romper Crochet Pattern

This romper is perfect for infants from newborn through the toddler years.  The bust of this romper offers full coverage while the body has an open, airy quality that will help keep baby cool in these hot summer months. I kinda want one too! 😉

I love how inexpensive this romper is to make. Depending on size, you may only need one skein of cotton yarn! Use cotton to keep the romper nice and airy – and durable. You could substitute a cotton blend but I would not use 100% acrylic.

Sizes: (NB, 0-3M, 3-6M, 6-12M, 12-18M, 24M, 2/3T)
