Thank you! I just used the luster dust on the rainbow. The butterflies are actually made with a mold though a cutter would’ve been much easier! I used a Martha Stewart mold set this one http://www.eksuccessbrands.com/marthastewartcrafts/Products/Flower_Garden_Silicon_Mold_43-00015.htm. If u have a Michaels they carry it there and u can use a 40% coupon they always have.
