Rag quilts were one of my first “just do it and see what happens” projects. I am no sewing expert. I should probably lead with that disclaimer. I follow the “Hail Mary” school of sewing, in which you ram your foot down on the pedal and hope for the best. But as I do these projects, I am learning more, which is part of the point, I guess.
Rag quilts are an easy place to start. To make one, I would recommend that you invest in a rotary cutter, ruler and mat. If you watch the Joann Fabric ads, you can get a coupon for 40% off any item and purchase a set that contains all 3 for about $15. You can make rag quilts out of any fabric that frays in the washer. I like flannel. Some people use homespun cotton or denim. The nice thing about these quilts is that they do not require a backing, binding or actual “quilting.”
You can find a nice tutorial here. If you want to make a different size, this website shows you how many squares of each size you would need for crib, twin, full, queen and king. Here you will also find examples of other fabrics that rag.
As far as your pattern goes, you can do a simple alternating pattern with 2 fabrics, a diagonal pattern, etc. Or go for a scrappy look. Its all good.
Here is one of my rag quilts. Its my favorite. It has no pattern. I bought 5 or 6 coordinating flannels and just laid them out. Its a crib size, but longer than wide. Its a good size for laying out for a clean place for baby to sit.
