I acquired some lovely blank jigsaw puzzles from The Works (larger and cheaper than Create and Craft) and used some of the pieces in these two cards as a mat.
This card was created a few months ago for a Craft Stamper Challenge - Altered Games pieces. The flower was created by stamping and distressing old bingo cards. I used Tim Holtz Bingo Embossing folder on the brown mat.
This card was created for a challenge swap - theme buttons and jigsaw pieces.
Although the cards were created several months apart, you can see the similarities.
