I don't know if you all have figured this out....but I just figured it out for myself! :mrgreen: I am making a quilt that has some pieces that are white with whiter polkadots. Once cut it was impossible to tell which side is the "right side". Totally by accident :wink: I discovered if I lay the piece on the dark cutting mat and flip back and forth, it's immediately evident which is the right side!!!!
Hope this helps you all! :mrgreen:
