Stamping on felt ?
 

I need to stamp on some felt. I plan just to stamp in black onto coloured felt.
I have staz-on, memento, versafine, palette and SU! dye ink.

If you've stamped on felt, please make a recommendation!

Well, I stamped letters and numbers only and I used craft paint with textile medium added so it was washable...What are you using as you stamp? What will it be used for?

Not quite sure what you mean by what am I using as I stamp - but I am using just regular old red rubber stamps if that is what you are asking.
I am stamping some felt pieces which will hopefully be part of page in a felt activity book for keeping small persons occupied and quiet.

I've had success with Palette inks on felt. Good luck!

I would say Staz-on, and i'd do some tryouts on a scrap piece first, to make sure the ink comes out a strong enough colour, in case re-inking the pad might be needed.
