Ok so it looks like I can do zigzag or lengthen the stitch for wavy with my walking foot and use the bar to follow a seam line to keep it straight (I hope that's right) but I should not try a decorative stitch with the walking foot? I have never tried quilting with a regular foot since I'm worried it will bunch up and make tucks on the back. So according to Prism99 it seems like starching the back alleviate this? Do you iron the starch or just spray and let it air dry? I've never heard of this before. I have spray basted my sandwich together and am ready to proceed.
