This is a great project for beginners and the finished blankets are PERFECT for babies...just the right weight, soft, and bigger than the flannel swaddlers from the store so baby stays swaddled up tight. They are the blankets I use most for my babies!
To make your own double-sided flannel baby blanket, you need one yard of flannel for the top, 1 yard of flannel for the bottom, and a spool of coordinating thread. Cut the two pieces of flannel so they are equal sizes and straight/squared up on all sides.
With right sides together, sew all the way around the edges, leaving about a 5 inch hole for turning it right side out.
Flip the fabric right side out, push the corners out until they are square, then press the edges smooth and flat using an iron. Don't skip this step! Trust me---if I say you should iron something, it's a necessity because I hate ironing! Using a decorative stitch, sew all the way around the outside of the quilt. This should seal the hole used to turn the quilt right side out. Now stand back and admire your handiwork! You're all done!
If you really want to impress your friends, try the self-bound flannel baby blanket. It looks so fancy, but it's not much harder to make!
