10 Best Gelli Printing Videos! Stamping with Gelli Plates Gelli Arts, the makers of the Gelli Plate, produce great videos. Two of my favorites demonstrate how to stamp with their plates. Gelli Stamping Layered Circles uses 3 sizes of the round gelli plates together with stencils and texture tools to create a colorful, layered journal page. Stamping with Gelli uses the smaller 5″ x 7″ and 3″ x 5″ plates as stamps to make some fun patchwork journal pages.
