2 months out and I hate it! Now what?

So Its two months out and I’ve spent the past 12 months compiling bits and pieces to DIY my centrepieces. Today I put them all together and I hate them. They are what I envisioned, but actually seeing it, it looks tacky and cheaply done (after hundreds of dollars) and while I keep trying to tell myself the the wedding is not about the centrepieces, all I can picture myself being at the reception and cringing everytime I look at a table. Ugh!
Has anyone else ever been in this situation? What did you do?
