This challenge was to use a technique that you haven't used before and make a card.
I have chosen the stained glass technique - see tutorial on Splitcoaststampers
I found this a lot easier than I thought to do and here is my entry:
The colours of the bird graphic are just so vivid using this method. I have used Bashful Blue and Very Vanilla cardstock which I embossed on the Cuttlebug using the Birds & Swirls embossing folder. I cut a square out of the VV cardstock and attached the vellum underneath so that the background was the BB.
Give this a go - it's so effective and easy.
