I got this cardboard triangle from my mother, who is an avid sewer, knitter, crocheter, and all around maker of crafty things. So, I decided to make a Christmas tree, out of various things. I used acrylic paint for the base. The embellishments are ribbon, buttons, coins, stickers, confetti, etc. Here are the pictures of the progression to the final product.
This is the original cone.
I used brown paint instead of green for the tree because that would be too traditional.
