I enjoy making my own stamps and stencils, particularly using my Silhouette Cameo, but I also enjoy making glue gun stencils, which are about as quick and easy as you can get.
To make glue gun stencils, all you need is a glue gun, a teflon craft sheet, and a design. You can make stencils using freehand designs, or if you have a transparent teflon craft sheet, you can place the design underneath and trace over it. Today I was short on time so I quickly made several freehand designs.
