Sat in the sun in the backyard and worked on the seal etching. The end is in sight now, well at least with the rock. But the seals shouldn't take anywhere near as long to finish as the rock has. The rock still needs shading to make it look more 3D, but that is just a case of darkening some areas the sun wouldn't be hitting.
Sketch #130. If I can't think of anything to sketch, a tool or DIY supply is easy enough to find in this house to sketch for the challenge.
