Day 2 of Insider at Online Card Classes brought so many amazing ideas, that it will take me a while to work through them all. There was a real focus on using acetate, and as I don't have any, I couldn't use it! One idea was immediately workable for me, and that was Jennifer Rzasa's window card. This is my version.
I used PTI Strawberry Patch stamps. Colours are Hero Arts Pale Tomato, SU! Gumball Green, Daffodil Delight, Memento Tuxedo Black.
The technique called for carefully aligning the outside and the inside and then colouring the inside. I only had one stamp that was big enough (and not a background stamp) to work with this technique, so Strawberry Patch it was. :-) The inside is BRIGHT.
