Still have no idea what to do...

I didn't DIY, but I used (for half) babys breath and hydrangeas for the centerpieces. The BM bouquets and GM bouts were all babys breath and they turned out great and it was inexpensive ($20 or so for each bouquet and I think the centerpieces were $65 or so).

You can order baby's breath and other types of flowers in bulk from Costco, Sam's Club or Fifty Flowers. Maybe buy some mason jars in bulk at Michael's or something? Or go to the dollar store and get cheap vases and do a mismatched vase type of look with a couple of flowers in each? Look at Pinterest for some ideas.

Go to the supermarket or local florist. Get some cheap colorful bouquets or roses... Roses around here are now 2 dozen for ten dollars... Go to Dollat Store and get some vases. Voila. I'm sure you can whip something up and it will be pretty but you have no time to be picky! Good luck!

What kind of theme are you having? I did my own centerpieces, one small arrangement and one bigger arrangement. I used two different sized mason jars for the arrangements, and smaller jars for floating candles along the table. The arrangements were simple. Maybe pick inexpensive flowers like these? Also, go with a big bloom because you'll need less of them to take up space.

Here's the smaller arrangement

You can do simple empty wine bottles wrapped in lace or something with one or two having a single flower or just a few flowers.

Yall are amazing! Lol and you ALL have got my wedding mojo going now! Thank you!!!!!
