I just finished the bent creek signs of winter into a door hanger. It was great. I think it looks pretty spiffy. The tip I learned from my book was to cut an L shap at the top and bottom for example: L L but picture the second L flipped. Then fold in the sides and put the top down. It helps with mitering the corners.
Well the quiz didnt go so well but I will do well on the midterm I have to. Hope you like my finish.
