They can’t all be perfect!
When you’re making something and all goes terribly wrong, just call it “ART!” and all is absolved.
This is a so-called tumbleweed print.
I let this print while I was at work and was hoping for a different surprise. As mentioned already, this is another piece of “art” for the bin.
@Henner_Zeller That’s a perfect term for these! I’m going to have to remember that.
A time lapse camera next time can create a nice clip of how “art” was created.
To me, the surprise is usually a perfect print! If you are expecting it to work perfectly every time, this is not the hobby for you… 
@Alan_Clegg the disappointment is worth it 100% when you get the print right.
Looks like a spider on pesticides
