After watching Jenny from MSQC use her rotating cutting mat, I want one! Have you thought about making a couple of Quilter's Stillettos? I used the instructions from Quilt ville ( one word, spell check keeps changing it on my ipad) in the tips section to make myself one and surprise, surprise it is really handy. It is perfect for keeping the seam allowances down when sewing over them by machine and is strong enough to remove stitches that I want to pull out of a stitching line. They are made from the metal turkey skewers that come 6 to a package for about $2.
