re: Red gumpaste - a sticky situation......

I’m not sure he will dry as hard as you need it to paint the lines. It has happened to me specially with black, when i made the lego figurines (3 days before the delivery ) the orange and grey ones were hard but the black girls never get hard enough so i needed to use toothpicks because their bodies were so elastic that they fall.
So if you have time to make another spiderman i will try CMC, or you will be struggling with the sticky one, and in a rush to make a new one a few days before.
Hope it helps Ü
