I've read about people using craft foam for applying CA. But, there are a plethora of options available online and at craft stores. If there is a particular brand or type you use that I could order online, please share the link. Thanks!
Here is a link to the stuff I use. Comes in lots of colors but we use the white. One sheets does lots of pens. We cut ours in about 3/4 in squares. Michaels has 40 percent off one item coupons online almost all the time. The foam totally transformed our CA experience.
Recently bought it to give it a try vs paper towels. First suggestion....Use less than half of the amount of CA you would put on a paper towel. I tried it for about 10 pens and have gone back to paper towels ( I think). Could be my pt technique is just more practiced but I feel like i get a smoother application.
