Water-based, dimensional, and pearlescent with a touch of glitter for additional sparkle and texture, Lisa Horton Dazzle Gel Paste will let you add a shimmery pearlescent-glittery look to all types of projects. Use it with stencils, apply it randomly, or even thin it with water to make it more paint like.
Some colors lean toward being more transparent and others are a bit more opaque. All of them look great on both black/dark and white/light surfaces.
