I bought this stamp for my daughter and then, when the kids and I were playing with stamping, she said she had never used it. In fact, she forgot ever having seen it before. Now that is a stamp that needs some lovin'. Yes, this is a very large stamp to ink up using a marker.
I colored it pretty much as shown on the index image on the wood mount, doing a lot of blending with the colored pencils. I was working on a rough cardstock so it was not solid color when I was done. I used a colorless blending pencil when I got home to smooth out the color.
I stayed with simple color blocking for the background so as to not compete with the large, busy image.
