Permanent Markers & Fabric Paint

[spykitten.livejournal.com]

I'm going to stencil an image onto a t-shirt with fabric paint. Could I then colour on the stenciled painted image with magic markers once the paint is dry? (Magic markers = permanent markers for most surfaces) Will that withstand washing, or will it react oddly and/or flake off?

(The reason I ask: I only have white paint but I want the image to be pale blue on the black shirt. I have a pale blue permanent marker and it seems to be the perfect solution...)
