L-shaped stamp positioner
From Craft Wiki
A stamp positioner for a wood-mounted stamp (or another type of stamp that you've placed onto an acrylic block) consists of two parts: an L-shaped block with a 90° corner and a thinner sheet of plastic. To use, simply
- Place the sheet in the corner of the L-shape
- Stamp your image onto the sheet by placing your wooden block right in the corner and pressing down
- Now place the sheet (with the stamped image) onto your project, right where you want the final image to be stamped
- Place the L-shaped piece around the sheet
- Remove the sheet
- Stamp your image onto your project by placing your wooden block right in the corner and pressing down
