I built my own Christmas tree. (Actually I made several and gave them as gifts to dear friends.) It was easy to do and they are adorable.
Drill hole in 2 inch wooden block. Prime, paint and collage block; use E6000 to adhere glass pebbles on bottom of block for feet. Attach assorted bits of paper, book pages, ribbon, lace, candy wrappers and the like on a 16 penny nail. Build up layers and add a topper. I used a swizzle stick I saved from my recent cruise and added a bead. Adhere the nail to the block using E6000 (insert in drilled hole). Wait 24 hours for it to cure and voila! a Christmas tree!
