I have made a small pounce using cinnamin, and had no problems. I just used a sq. of old fabric, put in a spoon full of cinnamin, and tied it with thread. It did not make any stains. However, I would do as was suggested, and try it on a sample of your cloth, to make sure. All fabrics are not created equal! I have trouble with a lot of the pencils not marking well for me. You can also get the regular pounce powder at quilt shops. I believe it was John Flynn on Simply Quilts who used cinnamin. Was also used in "the olden days" Good luck. I love SB Sue!
