Youdraw is a website that used to rely on Java script but after a while of being down its started up again. The area you draw on is only an inch by two inches in portrait orientation. You have a thick and thin black pen and a thick and thin eraser. But despite the limitations if you played with it you could thin the black lines or reduce the eraser marks. I did thousands of drawings there as Christine M-B. I’ve done just a few since it’s started back up. They are trying to collect 500,000 drawings. I copied a lot of my drawings and added colour to them.
