This was so fun to color! The stamp is called Halloween Holler Spooky Tree and Cat and is available at Peachy Keen Stamps. The artist, Steve Yarbrough, shaded this stamp so nicely making the coloring process a joy. I colored this stamp with Loew Cornell Soft Pastels. Pastels are very easy to blend and are not a big investment. (I purchased mine at Joann's Clearnace for $3.97 for 48 colors!) I will be linking this project at Peachy Keen Stamps' Anything Goes Challenge.
