I've always wanted to try stamp carving using erasers. There are really good instructions out there on crafters' blogs on how to carve eraser stamps, like this one from mairuru (in English) and this one from matatabi (in Japanese) and there are also many other good craft books in Japanese about making eraser stamps.
So, I gave it a try. These are the eraser stamps that I carved over the past few days. I found it especially difficult to carve small areas (like the eyes). There are many many flaws, and I know that I need to continue practicing to improve my stamp carving skills, but I enjoyed making these. I used these stamp pads that can be used on fabrics. (I'm trying to make my own "tags" to use for my handmade items).
