A hint: when you get it taken out.....Use Spray starch (heavy); Spray, let it dry, press, turn over, REPEAT again -respray, dry, press, turn over... I learned along time of go to repeat about 4 times. Then it's nice and crisp, and shouldn't have any problems when you cut your triangle. Just be sure, when your done with the quilt, wash it. Starch will attrack bugs and that is part of the reason, we will find holes in our clothes, quilts and such.
