I had to wait to post this until after the gift was given, a college-mascot pillow for a beloved family member! Boy, this was fun to make. I first did a free hand "sketch" of the mascot on wool. How do you sketch in wool? I simply laid the wool out in an outline, and loosely needled it in (so it could be easily removed and re-positioned). Then, I loosely needled in all the details and began to really work on it. As you can see, the mascot is mostly black. I added black and dark gray Coopworth curly locks to give some dimension to what otherwise would have been one flat dog.
I felted onto polyester fleece, and used fleece for backing. I usually do this for pillows, as the fleece is softer than wool felt.
Have a Happy New Year! Keep crafting!
