I saw someone using this on Youtube and just had to order one. I use a lot of clear stamps with acrylic blocks.
This is so much easier than using the blocks, and trying to keep your hand steady and line the stamp up on your paper.
You just place the stamp on the grid, ink it up, and place it on your cardstock. The little foam feet keep the stamp from touching the paper while you make any placement adjustments.
When it's just where you want it, you just press down. Perfect placement every time. Love it!
I have a much larger one from Fiskars, but this little size is perfect for cardmaking and smaller images.
