This set consists of two silks, 18” square. One is a black and white picture with a birthday cake, two bunnies and the words, “Happy Birthday.” The other is the same picture, but in four beautiful colors. Using a changing device (such as a change bag), the black and white silk is transformed into the full-color silk. I like to toss four colored silks into a change bag, along with the black and white silk, and then reveal the colored picture. Add a break-away wand or our jumbo foam wand for a great routine. Note: These silks are not the same quality silk as we use in the effects we manufacture, but they work fine for kid shows.
