Like many of you, I went back and forth over ordering from Costco floral. I finally pulled the trigger and got one for a mock up because "there's no price on piece of mind". The garland is perfectly what I wanted. I just picked up floral from trader joes but it's the same kind Costco sells (rose, hydrangea). I will probably buy Costcos white filler as well. Most of the floral is just tucked in but there are a few green zipties too. The garland is so thick that it holds up well if needing to cut and disperse amongst other tables. The core is just 5" of bundled stem that can be cut with sheers. You can also thin it out to stretch the use as well. We disected 1ft of garland to make 4ft of B&G chair garland! It's heavy and a beast to manhandle so expect at least two people working each box. Finally, I left it outside in direct sun for 2 days without any type of foliage treatment. At 26 hours, only 2 leaves had browned. Highly recommend if you're looking for impact. Maybe not for you if you're looking for a soft and delicate spread like eucalyptus.
Other: candle cases, chargers are from dollar store. Floating candles are from Amazon (best price but I haven't checked burn time yet). Everything else are things I scavenged around the house for the mock up, lol. Plates will be gold rimmed and silverware gold. Not the best photo because I wasn't thinking about posting-- but hopefully this helps! Feel free to ask any questions.
