What can I use to mark windpro?

[Ackray]

I wanted to make diaper covers today. But I don't know how to mark up my windpro! The fabric marker doesn't stay or show up on it. What else can I use?

Thanks!

nak ball point pen or sharpie are good for tracing to cut out. cut inside the line if you don't want to see it on the finished cover. hth

I vaguely remember my grandma using some sort of chalk roller thingie a few months ago - not sure what exactly it was or where to find it...

I've used a chalk pencil. That's what most people used before there were fabric markers, LOL. Most fabric stores have them.
