does anyone have a tip for getting a clean edge when doing sgraffito? i've used every tool in the book, but am still getting a ragged edge. i need to work on bone dry clay (because the piece is large). i'm cutting thru 3 coats of terra sig. thanks for any suggestions.

I have to agree with Neil, but you might have a chance if your tools are literally razor sharp and you touch them up every few cuts.

You're also creating a lot of dust when working bone dry, which is hazardous to your health. You should be wearing a mask in a well ventilated area.

If you are working on a large piece you just need more plastic to cover it. At the door of my local large home improvement store is a stand of giant plastic bags that are used to bag Christmas trees. Every time I pass by I pick one up. They are a little thicker than dry cleaner bags. Stuff wrapped up in them stay moist a long time. Another trick someone showed me was to double layer the plastic with a misting of water between. The sgraffito is a breeze on leather hard clay. I have worked on a piece on and off for months.
