I used the sketch from Seize the Birthday and the colors from CAS-Colours and Sketches
To me, this sketch just screamed for a transparent window, with the snail going across. When the card is closed, you see the snail going across the front. And he (she?) is still there when you open the card. Placing the inside sentiment was tricky. I could have put something across the bottom-grassy area, but I'll save that for a handwritten sentiment.
I used the stripe pattern paper to cover the various papers from the front -- and only now realize I should have continued the green across - - - oh well -- next time ? ?
paper: PTI cardstock, Echo Park "Hello Summer"
stamps: snail- There She Goes; sentiment - unknown
acrylic - I cut out of some packaging
Spellbinders nestabilities for cutting the circles
Hope you are having a Happy Day and thank you for looking.
