Icandothat.... I also used ordinarly copy paper and it worked just fine. As Lesley said use a small stitch and it rips out just fine. Just be sure you donīt leave yourself with a huge amount to do at a time. Rip them out as you go and remember to put the details on the front on a piece of paper so you know hte name and number of your block.
I have a couple of strays, Will have to go look
