ok..I am doing the pinwheel project and since this quilt is going to be my youngest daughters I let her pick out the colors and cloth..I did not stop to think or question the cloth and its a 100 percent cotton broadcloth or so the tag said..Its like working with silk, no matter how many pins I use when I go to sew it, the material moves around a lot and trying to line up the edges and keeping them lined up is a nightmare..Is there anything I can do to help keep this fabric from moving? And its so super thin, when you hold it up you can see thru it.Its like working with air
