I do - so I made a bookmark for Cards of Maria:
I've used patterned paper from Graphic45, white cardstock, Tim Holtz rubberstamps and distress inks, ribbon and small alpha stickers. I also covered the bird in Crackle paint, to make it pop out a bit more - the bookmark seemed a bit boring to me so it needed something extra. I'm not a fan of purple, but I'm quite pleased with how this bookmark turned out - I even LIKE the colours!! :-D It's good to challenge yourself to use things and colours you usually don't.
We'll see what I'll challenge myself with next time... ;-)
