|I have always struggled with cutting my fabrics precisely - somewhere between tracing the tissue patterns and cutting the fabric I find I go astray in a way that becomes very noticeable when I go to sew my mis-matched pieces together! So now I simply lay a sheet of freezer paper over the tissue pattern with the plastic side down, trace the appropriate lines onto the paper side of the freezer paper, which is the side facing up, then I iron that freezer paper directly onto the wrong side of my fabric and I cut along the traced lines! No shifting patterns while tracing, no shifting fabric while cutting. The freezer paper peels easily away when you are done cutting. AND as an added bonus, with trickier, slinkier fabrics i somtimes just leave the freezer paper in place and sew right through it!! Works like an utter charm. The stitches act to perforate the paper and it can easily be removed afterwards, although you may need to tweezer off some of the little shreds. It's very much like ripping loose leaf paper out of a notebook.
