Well, I clicked onto a blogsite today and have entered a challenge from Mary at stamps-paper-ink.typepad.com. Her challenge is to create a card with one layer only. No embellishments. So I used a play on words by making layers with ink only. Check out her website, the contest closes Aug. 31 but you need to mail your card to her by that date, so you need to move.
Here is my one layered card
