I dunno how much this really counts as DIY since I technically didn't make any of it, but I did all the work so I count it.
Everything came from Dollar Tree except the sticks and the food coloring; the sticks I cut off of a tree in our backyard for the test run, and I already had the food coloring from a cake I made a couple weeks ago.
Total cost per centerpiece: $6.31 including tax (used 1/2 of a container of floral gem things; used 1/4 of a pack of tea lights)
The silver frame is there to act as place card type thing. It's not included in the centerpiece itself. I'm still debating it. Silver is one of our colors, but I'm debating the overdoneness of frames as place cards.
Fingers crossed for picture attachment.
