Hello! I am not a cross-stitcher, but my mom was. She died in March, and for Christmas I want to frame a piece of cross stitch for my sister. I am attempting to do the framing myself, but I'm stuck at the first step. The cross stitch that I'm framing is a piece from a quilt Mom was working on. On the background of the fabric are blue dots which (I assume) are supposed to be quilted. But mom didn't get that far. I was told that if I wash the piece the blue dots would come out. But they are not! I am washing the piece in warm soapy water, but the dots are still there. Can someone tell me how to get them off? Thanks!
