I agree with the glue stick..works much better than pins for me! Also..if it is a large piece and is sliding everywhere, I grab a couple cans of canned veggies to anchor it. As long as you've glue-sticked it..you shouldn't need a walking foot, unless you already have one. I have 2 walking feet and never use them..I find them cumbersome and a pain to work with..I sew lots of silk and satin with a regular foot. Also, you should use a ball point needle to avoid breaking the fibers.
