This was done using a 24” X 20” cotton canvas, skotchgard water shield spray, 8” letter stencils, pink and blue tempera water based paint. Dilute the paint with water before putting in the guns. We had enough water guns for the guests to choose from. Either pink or a blue gun and when we turned the sign around the guests sprayed and saw the message “it’s a boy” #genderreveal #genderrevealideas #genderrevealparty #itsaboy #babyshowergamesprizes #babyshowerdecorations
