This first card used 20 dragonflies punched out of transparency that I'd colored with alcohol inks. The Asian image is by Sonlight Impressions, the sentiment by Inkastamps, and the background paper is DCWV's Far East.

For this second card, I took the challenge more literally. LOL! I was looking through my supplies to see what I had 20 pieces of, besides flowers. I came across the googly eyes. Then I remembered my Maui cows stamps and was hoping that there were at least ten cows in the image that I was thinking of using. WOO HOO! There were exactly ten of them. So, the main image is by Maui Cows and the sentiment is Cowtown Stamps. I used the bloom dots Cuttlebug embossing folder to add texture to the red cardstock.

Twenty sounds like a lot, but it can be fun to see how quickly things can add up on a cardfront and still not look overpowering.
