For the background on the dragonfly card, I used starch and cling wrap. It's Brusho & Spray Starch #45 in my technique binder. Pictures and description on this blogpost. I'll email the set to you FREE with an order of $25.
For the butterfly card, I embossed the butterfly in gold, then used an Aqua Painter to brush on the color. The background on the left was done with bubble wrap, and is #44 Brusho, Starch, Bubble Wrap in the technique binder.
