Last year I had some scraps of plywood from a home improvement project, and I decided to make giant Christmas Ornaments, which I'd planned to hang in my front yard tree. However, as I was in school at the time, I only had time to make two, so I gave them as gifts to my two professors.
How I made them:
For the round ornament I traced the rim of a bowl on a piece of wood and free-handed a top, then cut it out with a jigsaw.
I free-handed the reindeer, but since I couldn't get the jigsaw to cut such small details, I just cut around the edge.
Then I painted and sprayed with clear acryllic, and finally put a little eye-hook in the top to hang them.
