Thank you, it totally does! It's not so much a budget thing, more like I don't want to lay down a bunch of cash if I try out coloring again and decide that it's not for me.
Last time I tried doing color sketch cards, I used acrylic paints, and then laid the ink down on top afterwards. Not horrible, but not great - plus, the acrylic is a lot thicker and difficult to deal with.
Thanks again! I think I may just try flat color at first, then maybe layer shade on if I'm feeling brave.
