This website was my favorite out of all of the ones i tried. it was very easy to use and you could create beautiful images from just a doodle. How it worked was you draw and image and then the website begins to make it look like a sketch by the use of connected lines and scribbling over the image you created, while still keeping it looking like your own. You could choose, line colors, line speeds, and line thickness, etc. This was such a cool website and i loved experimenting with it.
