I was thinking which could replace wood handle for stamp. I had tried cardboard, tack-it and magnetic sheet. All of them are useful, but tack-it is good for eraser stamps. You can use tack-it to stick wood and stamp, and recycle use them for other stamps with same wood. The only problem is the tack-it will dye the stamp and wood, but I don’t care. Why did I say it’s only good for eraser stamps? I did try stick the hectograph with wood; however, it didn’t work well. Hectograph needs strong pressure to print; however, it’s better to stick it with sponge tape on the back. Therefor I tried another way – magnetic sheet. I stuck sponge tape on hectograph and the other side with magnetic sheet. Voila! You can use any magnetic stuff.
