In addition to ATCs there’s also APCs. Altered Playing Card. Most people leave a little bit of the playing card visible so you can still see the number and suit. But otherwise you can use the card just as an ATC base.
The prompt for this APC was it needed at least 12 layers
Wow, they are both great!
And the 12 layer requirement would have totally intimidated me!
Do you play around with a layout before gluing down?
I find that I cover up what I wanted to see and realized maybe I need to do a “mock-up” first
