Your PDF attached to the March/April challenge is promising. I'll give it a go. I tried the Fun with Wilbur, Vol 4, before.

I'll have a shot at it tonight. 100 passes with the precipiton tool! Fingers crossed for results.

While you're here - when should I use precipiton vs incise flow? I've seen a tutorial with countless incise flow steps, but only a few precipton steps.
