In this week's Wednesday Workshop, I'll show you how I use a clear block with lines to stamp letters in a straight line on to Gelli papers.
Something I didn't mention in the video is that when you are done with the stamp block, you can clean it with rubbing alcohol and a rag. When the stamps lose their stickiness, you can also clean them with rubbing alcohol and a rag.
