I found these plain ole paper mache fruit in the bin at Micheals as you are in the check out line. They were a dollar a piece and I bought the apples and pears. Some came in packaging some did not.
After it is separated I cut it into four sections and use two sections per ornament. I then take gel medium, or mod podge would also work and a paint brush. Brush on the gel medium over half of the ornament starting at the stem and moving to the bottom. Then take the first section of napkin and place it on the top and start to paint medium over the paper napkin, it might crease and crinkle but you can smooth out most wrinkles with your finger. Once it is on make sure that it is throughly covered with medium and do the other side. Make sure you get all the brown covered. Be careful at this stage since your fingers will be sticky and can pull and rip the side you have put down since you are holding it from that side. I often have to go back and fix areas, just be careful. Once the whole surface is covered with both the paper napkin and the medium let it dry thoroughly. I make dozens in one sitting as it is messy and I want to be able to clean my fingers off without having to go back and do more.
