I recently received my smaller, 3" x 5" Gelli Arts® Plate. During my first project, I left mask to keep wire area so that I could come back and stamp with the small Gelli Arts® plate. I realized that it might be better to shield or isolate the work around it so I created a frame with the 3x5 opening. I also determined that I could make a 68 frame to isolate and only use that portion of my larger plate. Turning it into the 6x6 size without investing in a 3rd plate. Wow, you could actually do this in any size creating a variety of personalized Gelli Arts® plates; however, I would recommend the 3x5 gelli with the 8x10 so that you can stamp onto the larger plate too.
