I get that a bit as well. I'm usually extra careful now to let the wet
Sharpie crap dry thoroughly, and then redraw over top of it once or
twice, until it's nice and "dense" looking. I sometimes use a regular
"fat-tipped" marker for wide stuff too.
I was wondering if there were any easy techniques for masking really
large areas, like the whole back side, for instance? Seems like it
might help for doing double-sided stuff, if you could hit it one at a
time, while covering the other side with tape,etc. I hate trying to
protect the delicate toner work on one side during all the pressing
and heating for the second one.
