I do rarely colouring my stamped images. Usually I don't have the time (or patience?) for it.
Although I am really not that good in colouring with alcohol markers I like the style as long as the card still fits to "clean and simple".
I think even some cheaper markers than copics work nice. The Rotbart Delta markers cost only about 1/5 of a Copic marker and in my humble opinion they turned out great:
I mounted my focal image on a white card base so the bleeding ink won't show through the back.The bleeding through process can be avoid with the correct paper - Copic do offer some. But for me, it is too pricey so I used my Papyrus Paper, which I have on hand.
