Hi all!
Looking for feedback/insight on how many stems I should actually be planning for my DIY wedding!

Ingredients:
Focal flowers: Ranunculus, carnations
Filler flowers: Yarrow, spray rose or lisianthus
Line flowers: snapdragons and foxglove
Greenery: TBD any suggestions based on floral choices?

I have to fill 45 bud vases(3 stems per vase roughly, so about 145 stems total there.), and make 8 medium centerpieces.

I’m pretty stuck on centerpieces and how to estimate how many stems of each might go there

Any feedback or insight is much appreciated!!
