Thanks for the replies guys. I don't know why for some reason I was thinking copics where the standard for cards... I would love to get those amazing copics, but oh boy, are they expensive! I can't afford those right now, and knowing me, I would probably need a loooooot of colors...I have a few acrylic paints, Schmincke gold metallic powder, watercolor iridescent medium and a lot of tubes of watercolor 5ml and 15ml that I've been collecting and I haven't been using as much as I should...
I just bought the versafine stamping ink..I think this one is pigment based, so hopefully it won't smudge with water.
I have hot press paper, so I guess I will be experimenting a lot!
