i have a good-sized collection of wood mounted stamps that i shied away from using due to placement issues. this jig is super simple to use so i know i will be getting more use from my stamps. my favorite use for it has been re-stamping over an image that didn't come out perfect - the alignment is perfect! wish i had gotten it sooner.
I have trouble getting stamps lined up correctly and this tool really helps. I did watch a tutorial for using it because the instructions that came with it were not real clear to me.
