These trees are all made from multiple "found" items. A couple of years ago, I found a stack (probably 50) of cardboard spools from thread. I wasn't sure what I was going to do with them and the woman wanted $5 for them, which I thought was a lot considering I didn't have a plan yet.
I also had a box of door knobs that had not sold.
I had also purchased two bolts of upholstery fabric at Goodwill, both were red with different checked patterns. I tore the fabric into strips and wound them around the cardboard cones. I found some old candlesticks at Goodwill, spray-painted them and glued the cone to the candlestick. A simple rusted jingle bell tops it off.
These are really simple and I sell them from $7.50 to $10.00 depending on the size. I have sold nearly all of them and now am constantly on the hunt for more of the cones!
For the doorknobs, I totally stole an idea from Pinterest! I bought inexpensive bottle brush trees from WalMart, remove the base and glue them into the door knob. Again, I cannot keep these in stock. Alway on the look for door knobs now! These simple items have become a staple in my booth during the holidays. They easily pay the rent and the profit margin is high. Surely you have a door knob laying around somewhere....
