I tried Carol Doak's foundation paper, but it wouldn't feed into my printer unless I hand-fed it one sheet at a time. That was a pain. I thought it was too flimsy and easy to tear. My regular multi-purpose printer paper works just as well. Just be sure to set your stitch length to a very tiny stitch and it should work fine. The short stitch perforates the paper (as in, tear along the dotted line), and it's as easy as anything else to remove when you're ready.
