Upgrades always leave us worse off, so why do we do them? I took 4 months before I finally did it, and I'm SORRY.
Slip trailing...got new pens...tried them with fantastic results. THen got a new "matt clear" to put on top of things. Not at all matt. And I think it's why one of the slip trailers messed up.
All the heavy lines on this new piece are the underglaze black, and the clear is all the Matt (ha ha ha) clear.
They were both fired on the same schedule as well.
