There is such COOL stuff being used in the quilting world! I just found this via a Pinterest pin; it's such a great idea!
Using Glad Press-n-Seal for Free Motion Quilting
My next question is this: with any of these (paper) piecing/sewing methods, I am envisioning a MESS under my stitching of (paper) that I simply won't be able to get out without a) ripping my stitching or b) at the very least pulling/stretching my stitching. With a 12 SPI spacing, it would seem an ugly process to rid a quilt of anything that is used to guide the stitches.
What am I missing? Is there another step or tool that I need to easily remove the residual paper/plastic mess?
