Centerpieces come with my venue and they are exactly what i wanted I'm just putting a swirly silver branch in it (they are called something I just forget lol) and putting diamonds and petals on tbe table
DIY, but only because we happened to choose something we actually can handle ourselves. Our centerpieces will be silver mercury glass vases (making myself using Dollar Tree vases and Rustoleum Mercury Glass spray paint) with fresh baby's breath inside. It will be surrounded by scattered white candles on slabs of birch that we're cutting from the annual tree clean-up at the family cabin.
If we were doing beautiful floral arrangements or something elaborate, I'd absolutely go pro as we simply don't have the skills!
