And I thought fabric markers were made not to bleed on fabric!
I guess it depends upon the material… If you are using cotton, they probably do great – as do some other non-fabric markers. 
But on polyester… you need the Perfect Crafting Pouch to stop the bleeding!

These tests were all done with Marvy Uchida Fabric Markers on Wright’s Twill tape–both found in a fabric department.
