I went to the stores (online) to find a pair or trio that would be perfect for the top shelf. Well! Trees are expensive! I was thinking I could find an un-decorated one for $10, but the cheapest I found was $20.
I just knew I could do better, so I picked up a couple styrofoam cone from Joann (60% off coupon, yo) and headed down to my amassed Christmas decor collection in the basement.
I wrapped garland around the cone, adhering with hot glue. I used stems from an old, ugly swag and found some picks that were meant for another project to use as decorations. I set each tree on a tin, but didn’t attach them in case I want to change them up later on.
