Diamond art release paper acts as a barrier between the adhesive canvas and the environment. It protects your project and allows for easier section-by-section work. To use, peel off the plastic from your canvas and place the release paper squares side by side on the canvas, covering the entire surface. Then remove release paper one section at a time as you work.Details:White4" x 4" (10.16cm x 10.16cm) sheet size200 sheetsSilicone
