How many flowers does it take to make a sphere??

How many flowers does it take to make a sphere??? That question comes across many times, so here is the fail safe recipe.
What size sphere you have score it gently, don't cut, just make a mark around the sphere marking it in half, then mark the halves in half = quarters. This is usually plenty for the smaller spheres. Then take a flower, make a mark in the foam where each flower will be inserted,making room for it to open if that is the goal. Then multiply that number by 4 which will equal the total amount needed. If it is one of the larger spheres score into 1/8 or 1/16, then multiply that out.

Thank you all for the great questions, it stems simple ,but when we are in the middle of something it is harder to see the end. I don't even have half of the answers but I know people that I can ask. The best part is that we all keep learning, sharing and designing.
