I just ordered my table numbers off of target of all places! I was planning on DIYing them, but it seemed like I was going to spend $20-30 on materials and didn't seem worth the time and money. The ones at target I thought were simple and pretty.
They are on sale for $7.19 for 40. Here is the link if anyone is interested.
