We usually do 45"x60" for our prayer quilt ministry, for infants and small children 36"x36". Rail fence is a favorite pattern for me and Turning Twenty. A rag quilt works really well. Just whatever you wish. Some ppl even just layer 2 pretty co-ordinating fabics with batting.Sew up pillow case style. There are lots of free patterns and ideas online. Just Google free patterns, prayer quilt ministry and the Linus project for kiddos. It is a wonderful blessing that flows both ways!
