Want to make one? All you need is a foam tree and some thumb tacks - mine are from the dollar store. I used two and a half boxes to cover the entire tree.
Turn on a movie and start pushing them in! I pushed in a line of tacks and then put a line of tacky glue on both sides of that line. The tacky glue helped keep all of the tacks secure.
Don't worry about making perfect lines, overlap the tacks as necessary, and don't be stindgy with the glue! I recommend using tacky glue because it drys 100% clear and you won't have to deal with the heat or gross strings from hot glue. Hot glue + metal tacks = hot, hot, hot tacks and unhappy thumbs! :)
Aren't they beautiful? LOVE! What types of Christmas decor do you collect?
