FriXion Pens
From what I've read, many of you use the FriXion pens to mark your quilt tops. I was going to try to buy some online, and gosh, there seem to be several kinds of FriXion pens. I want to make certain I get the right ones, the ones that erase with heat, before I buy, so any advice will be appreciated! Also, is there any color that does not come out as well? (My hindsight is 20/20 - foresight, not so much! Better be safe than sorry!) As always, thanks for your help!
