It’s no secret that I love baby blankets. While times have changed and pediatricians no longer recommend that you let infants sleep underneath blankets (especially not bulky crochet ones), baby blankets still make great projects to gift for decorating a nursery, to use as stroller or car seat blankets, or to use for “tummy time.”

This pattern was originally designed as part of a kit for Craftsy (now Bluprint). It was one of my first mile-a-minute (also known as strip-pieced) crochet patterns.

While the colors for this version are pretty feminine, you could also use neutrals for a less gendered project.

If you’re not sure what colors to use, try and get a sneak peak of the nursery. I find that most expecting parents are pretty excited when things coordinate!
