The Chameleon Pens are permanent alcohol inks so they will work on fabric however we suggest using the Bullet Nib - Not the super soft Japanese Brush tip as it could damage it if the fabric is too rough (however they are replaceable!) 

Another suggestion is to iron it before washing to heat set the ink,  just to be sure. I would also suggest washing it on it's own on the first wash just incase any of the colors run out a bit.


Some crafters  also suggests putting aloe gel around the outside of the area you are coloring (to act as a barrier) just incase the ink bleeds or seeps a bit when coloring
