I use to work for So Fro fabrics years ago we always tore fabric that was 100% cotton because it would tear fabric on its grain line which is important. Now days because of cutting
if you try to put fabric on its true grain you will wind up
loosing a lot of fabric I put my fabric on grain if I am making clothes but with quilting you are usually making small
cuts for piecing .I will however put my long border strips on grain .Sometimes you have to stretch fabric a little bit by tugging on opposite corners to square it back up but it will be on grain.
