The first quilt I ever made was without any instructions at all. I knew nothing except I had seen a You Tube on QAYG with the sashing between blocks. I had a box of scraps given to me that I wanted to use up. That quilt has every kind of fabric; cotton, jersey, lots of polyester, and that bumpy fabric. Of course it is a scrap quilt made without a pattern. It is on my bed now, and I see no problem with it at all.
