Hi I don't use washaway sheets. I use Heat 'n Bond lite. It is easy to sew through. I print on the paper side of Heat 'n Bond, then pat it with a tissue, actually lay a tissue on the ink side and pat it. As soon as I fugure ouut how to get them out of my camera I will send pictures. I put the enlarged pattern under the silicone sheet and lay the pieces on top of the sheet...when you peel them off, they are all lined up with the "cross hairs" in the middle of the pattern. feel free to ask quetions. I have done this with McKEnna Ryan patterns and it works well, however,I don't do much sewing on those, they usually are hung on a wll,
