I make a design but I cant find a way to make it into a cursor

Open an image in RealWorld Cursor Editor and click "Create Static Cursor" or "Create Animated Cursor" in "Cursor" menu.

And save once your done

If it is an image format (.bmp, .jpg, .jpeg, .jpe, .jfif, .png, or .rri), click 'Create new,' then 'create cursor from image.' Find it on your hard drive and click 'open.'

If that doesn't work, open it in another program, copy the image, and paste it into RealWorld Cursor Editor.
