Here's what I used to make mine:
Garland ties (Dollar Tree)
3/8" Dowel Rod (WalMart) - cut to 12"
Scrap block of wood - cut to 3" x 3"
Floral Tape (WalMart)
Drill and 3/8" Drill Bit
I also used our chop saw to cut the wood and a scrap piece of sand paper to smooth the cut edges of my dowel rod and wood block.
