I would make receiving blankets. Cut the 2 pieces of flannel WOF and the same length as the WOF so you have 2 squares. Round the corners using a plate. Envelope them together. Turn right side up and top stitch around the edges. Without anything in between they don't really need quilted. But if you wanted you could just sew a big X through them. If you wanted them a little fancier large rick rack could be put in the edge seams or use a fancy stitch when you top stitch.
