Easy to use. Simply prepare your vase & stone/marbles according to Liquid Illusions resin instructions. You will need to either construct a grid with waterproof floral tape on top of vase or use a piece of floral netting to hold your silk flowers in place while the resin sets. Mix resin according to package directions. Place marbles or stones 2 in. to 3 in. deep in vase, adding half the resin to them. Then pour the rest of the remaining resin into the vase. Design your floral arrangement and let set for 36 hours.
