I love background stamps. Especially the ones using dots. But most of the time I think them way too expensive. Hey, we are talking about some rubber and dots!
I just used some foamed rubber stickers (I got a big package in an euro store but you can get cheap foamed rubber stamps nearly everywhere!). I glued them on some wood (0,5 cm between every dot, I drew the lines with a ruler on the wood before).
I also made some tiny stamp...
Or you would rather like some distressed dots as background? Use some bubble plastic!
See the effect?
Or cut some foamed rubber...
Use the foamed rubber stickers itself as stamps!
Oh, and another hand carved stamps which I made after a paper cut out design...
(but to be honest, my knife was not sharp enough anymore)
As you see, I use just some wood leftovers to mount the stamp!
To clean them I use some baby oil wipes / towels.
And my stamp trials :)
