This is a really dumb question for someone who has been stamping as long as me.
I'm having trouble with the Memento ink smearing when I color with my Spectrum Noir markers if I just stamp and color. If I let it sit for 24 hours it's fine. I tried heating it so I wouldn't have to wait so long, but it still smeared. So the question is, How long do you heat the Memento ink to make it set before coloring? I must be doing something wrong!
(If it makes any difference, I have a Milwaukee heat tool. One of those black cylindrical ones.)
