There are actually a few patterns out there that would give you measurements. Take the size you want the quilt and squares to be and any LQS will be happy to figure it out for you. All of the rag quilts I have given out are loved ,washed,washed..... Since most are flannel, , they are so soft. I am doing one for a toddler now that my strips are the width of a 6 inch ruler and length of the fabric. They are fun and quick, just make sure to get the snip type scissors to save your hands. Have fun, jump in,oh yes, take it to the laundrymat for its first wash/drying, due to all the lint...
