Centerpieces under $10 , is that even possible !

PS - I spent about $75 in total, but my venue already has the table numbers I can use for free.

I think it's totally possible. My budget is about the same as yours (15 tables, too). Sadly, Canadian Dollar Trees don't have online ordering and I never saw any vases. I found vases from Dollarama for $3 each, gold charger plates for $1.66 each, then plan to fill the vases with planted flowers closer to September when gardening stuff is on sale.

I'm using beer growlers from local breweries with bulk lilies from Sam's Club. My favorite brewery was happy to supply empty growlers to fill out my collection, with a full refund when I return them! Bulk lilies were only $100 with free delivery.

The Dollar Tree/Store is your best friend and IKEA (if you have one around) The frames we're using for our table numbers were .99/ea. at IKEA. They're double sided and work nicely. I'll be spraying them silver/pewter color.

You can get 10.5" cylinder vases from Wal-Mart for $2.97 a piece. I ordered my orchids from Amazon and they were shipped overnight with free shipping and they were so cheap! I also ordered my LED submersible lights from Amazon and they were cheap also. It's definitely doable. I would have to check my e-mail to see which companies I used.

Maybe bud vases (dollar tree like someone suggested) and a few small candles and flower petals surrounding it?

If you go to the thrift shop, and don't mind mis matched vases, they are even cheaper than the dollar store. Sometimes 4 for $1. Then you spray paint those suckers or decorate them however you want in your colors, or a neutral cream/white/black. Stick one large paper flower in each vase. Whoever is setting up your tables won't have to worry about which vase goes on which table. Just mix and match! You can buy cheap paper to make the flowers online, use hobby lobby coupons as well!

Yep! Attached were mine. I bought the bowls off of craigslist ($40/15) and the floating candles ($25/30) from yummicandles.com and 1 dozen roses from a local grocery store.

ETA: the flower petals were $1 from the Dollar Tree

Yep! Attached were mine. I bought the bowls off of craigslist ($40/15) and the floating candles ($25/30) from yummicandles.com and 1 dozen roses from a local grocery store.

YES! I got all of my reception decor on sale at 80% off! I got everything I needed to decorate the ceremony and reception for a total of $47.83. Now I have half of it completed, I just need to finish the rest of my decor!

You can totally do it. I got the great 80% off last year in November at Micheals and JoAnn's.

I'd say if you were DIYing your centerpieces, yes. To have a florist professionally do them, no.
