Question:

Is there a fabric marker that will show up white on black fabric?

My dad has been in a local band for a year now and I haven't been able to go to any of the concerts. I want to show him I am interested in what he is doing by me and my friends going to thier next one in a couple weeks and acting like "groupies," rush the stage, and have them sign my band shirt. The only problem is they made up black shirts for their band so I'll need some type of bold white marker. I wear the shirt a lot so it would need to be put in the laundry, but i don't want the "autographs" to be washed out. Is there any suggestions? please include the brand and what store I might be able to find it at. (I need the marker or fabric pen before March 23rd.)

Thanks,
Tabbie
