I made this simple tool for the Scratch Design Studio. It simulates a paper folding when you press the button. There also is a wide choice of paint colours, and there's a pen thickness choice. There is a better pen quality on Turbowarp: https://turbowarp.org/1325142309?hqpen I'm trying to implement save codes but it's a little bit complicated...
Everything was done by myself. Made for the "Through the Looking Glass" SDS Scratch possibly creates lag, so don't draw too quickly. Thanks for all your comments! If you have any improvement suggestions, please let me know.
