There are specific papers made for this purpose. I've gotten them from Golden Threads and they come out nicely. I've also used tissue paper and it comes out fine too, except when used on darker colors, then you have this trail of white fibers between your stitches. I'm sure they are there with the other colors, you just don't see them. I also use the paper from Golden threads for foundation piecing as it comes out easier and puts less stress on the stitching. Good luck with the FMQ, it takes lots and lots of practice, but don't give up. :thumbup:
