For this card, I did do a lot of popping up of layers. Children seem to like seeing popped up layers and dimension. You can see the layering in this next photo.
For the inside I tried to off stamp/second stamp the Cucumber Crush number to lighten it up a bit. I thought that would allow me to write over the four, but as you can see the green is still bright and dominant.
See the product list below, and happy creating!
