Oh, almost forgot - here's one I did yesterday (yeah, another one-drawing-day lol) with a chisel point sharpie.
Some pics showing the building of the new easel - it's just a flat frame that leans against the board I clamp to the table.
Got it all glued and screwed up now and it's solid as a rock. Though at first it was a swiveling parallelogram - it could lean one way or the other with the horizontal planks remaining level lol! Had to attach a big rectangular piece of thin masonite to the back with several screws to keep it all squared up. And now I need to take the end of one leg to the belt sander to get it perfectly level. Need to get a pic of the finished thing.
It's made from some old canvas stretcher bars from the art school days I never ended up using.
