Activity for Alexandra

Hello lovely ladies and gents I have a dilemma. Our wedding colors are Navy Blue, Gold with Greenery. I have been looking at 2 tiers wedding cakes in navy blue and I don’t like any I have seen, I am more attracted to white, gold with greenery on them...

I am trying to figure out how much greenery to purchase to create an 8ft long garland I have 6 guest table and 1 love birds table. Please help 😩
