I haven't gotten around to posting a photo of my June Humble Artist's Swap card yet, so here it is! Here was our list of requirements:
No patterned paper
No neutral coloured cardstock
Must have minimum 8 layers
Must use 6 different stamp images
Do not use any embellishments (brads, ribbon etc.)
Make an embellishment from paper that counts for at least 2 layers
Do not use any stamp sets with Border or Background in the name
Whew! It always takes a little time to get your head around the project, but once you do, it starts to roll. I left the pink strip blank so that each person could personalize the card however they like. To see what the other swappers made, you'll see a list of their blogs down the side of mine - just scroll down.

I made five of them!
Stamp set is Card Word Puzzle; Cardstock is Garden Green, Olive, New England Ivy, Blush, Hollyhock & Baby Pink; Ink is Grey Wool; - all CTMH. Copic Markers.
