I also made a large receiving blanket for my son's teacher that just had a baby this week. It is mint green on the back even though it looks white. I will make a few bibs to add to the gift and send it on it's way this week. Finishing these items means I also finished my to do list for today!
I took 2 pieces of flannel, put them right sides together and sewed around the perimeter. I left a gap of about 4-5 inches for turning it right side out. I turned it right side out, ironed it, and sewed around the perimeter again sewing the gap closed. It doesn't get any easier that that!
This is a very large blanket. It was 1 yard by the width of the fabric.
