I tried a couple of different pens, but never used them on actual quilts, because I am concerned about what the chemicals might do over many years time. I thought about Pounce, but have heard that it aggravates Asthma. I stick with ordinary school chalk. I have not had any problem getting it off the fabric. I wipe it with my hand or a computer brush. Very happy with the results and 12 sticks in a pack for less than $2.00 is lovely for my purse.
