I've made a few rag quilts with 9" squares and 1" seams. Also, I've used standard cotton batting. I'm interested in suggestions for making one for my 5 year old granddaughter such as what type of batting (flannel batting, what is this?) size of squares for a child quilt (age 5), design...etc. I have already purchased dinosaur print fabric and 2 complimentary colors to use.
