These stamps are so versatile...I can't believe how inexpensive they are! I use them with paint and ink. The foam allows you to put pressure on each part of the stamp to get an even image (unlike my experience w/ some wood mounted stamps). If using ink, you just need a very light layer of paint--use a brush to brush it on instead of dipping it in the paint. I've used them with dye and pigment ink, both times with good success. I've stained them with so many inks by not cleaning them right away, and they still work as well as they did brand new. I use them all the time!
I love these stamps. They are so versatile. They wash off easily and were very inexpensive. I did loose some dots that were part of one of the stamps because I didn't realize that the stamp part can come unglued from the foam backing.
These stamps are just awesome - I use them all the time! They are such great shapes and add the finishing touch to any project - I have had them for over a year, used them all the time and they have lasted really well.
