They may work great but can you remove the ink permanently. That's the problem with the Fixion (sorry if its spelled wrong, early in the morning, not thinking yet) is that they work great but not always easy to get out, PERMANENTLY. If you contact the company they will even tell you they weren't made for fabric or any service where you need to make sure it is removed for the long hall. If its just the center line going thru the HST where you cut, then no problem because it'll be in the seam line
