Another question

[neweuropa79.livejournal.com]

I will soon be doing some Batiking (wax resist) dyeing on some fabric I just picked up this evening. Now, I was wondering if I drew the pattern I will be following on the fabric with a fabric pencil, you know, the stuff that comes out in the wash, will the pencil marks still be visible and in there forever because they will be held in by the wax over it? Or should I just go without a penciled in design and not risk it?
