A quick trick I use to erase a curve
I, like many artists, have tremor and wrist issues that can make getting a clean line, especially while erasing, pretty difficult. I couldn't find any line erasers so I made a bit of a work around. You have to make sure that you choose transparent as your color shade for it to work. I have also made a straight line but if you're low on space you can always just download one and then change the curve on the menu.
Hoping to have a basic shape set too but not sure yet how that will turn out and what it looks like.
Thanks for checking my stuff out and have a great day!
