the problem in fact is in deciding which card to enter!
I love patchwork cards and my previous designs used the 1" square, but I have made the latex ones using the hexagon punch.. After they are adhered to the base square I run them through the Bigshot with an Embossing Folder to give the look of a quilted piece before embellishing.
These ones use Midnight Muse, Gumball Green and Summer Starfruit.
My other card for this challenge is a flower Box card - it stands up like a flower box but folds flat to fit inane envelope- however it is not as bulky as a card in a box.
I have taught these in a class and they were very popular.
Raspberry ripple, Gumball Green and Summer Starfruit.( with Midnight Muse as the background)
