Wigglebutts is designed by Dan DiPaolo for Clothworks
Here is some info about Dan from the Clothworks website.
Most of Dan’s days are spent on his farm in Burlington, Wisconsin. From his studio window he can watch the corn grow, leaves fall, snow flakes flurry, and all the critters that find their home on the farm. Dan is inspired by his farm and his friends. Dan’s characters often begin as a doodle, an activity he engages in nearly constantly, and develop drawing by drawing. He believes laughter conquers all fears and brings people together. Dan hopes that his art makes you giggle just a little!
