Yes and it's easy to do. instead of sewing the two blocks together, over lap each block 1/4 - 1/2 inch wider then the rag will be and then sew it with each overlap on both sides of the seam. Do the same with each row, overlap both edges. You have an edge on the front and the back. It was how I made my first rag quilt using real denim from used Levi jeans using instructions from an old Farmer's magazine my grandmother use to get. That quilt is decades old in fact almost fifty five years old. I used heavy thread in my grandmother's treadle machine. The quilt is at my daughter's house last time I saw it.
