Hydrangeas make me fraid. So did fire engines for my daughter. Hydrangeas are such a large mass and they look great in an arrangement with many of them, or with peonies but these big white fluffs can create mass and holes in a colored arrangement. When I started this piece I put the yellow stock in first. 3 pieces which would anchor it. I had the clear and light blue stones in the glass vase so they had the opportunity to stand up straight but for some reason they listed to the left. I went with it, making the arrangement off-center, adding my puffy hydrangeas and then the pink spray roses. Wow, I had never let the spray roses open up so much. Their round form complimented the spike of the stock.
