I thought this was such an adorable idea, someone just posted the photo to my timeline! You must insert the toothpicks at a 45° Angle or the cupcakes may fall off. The styrofoam ball has a 5" diameter and holds 10 cupcakes. Cut green tissue paper into thin strips, fold accordion style and place it in between the cupcake "flowers" to give the illusion of leaves.
for a bridal shower (minus the lace/ribbon on tiers - solid satin ivory/party theme colour ribbon in lieu) - for a bachelorette party, ALL black (including the cupcake wrappers) and used either stark white or party theme colour icing.
