Redraws are a feature that allows you to copy other users' creations, continue drawing on them, and then post the work.
You can use creations for coloring, a theme, a layout template, and more.
You can make a creation redrawable at the time of posting.
However, permission cannot be revoked once a work is redrawable.
Creations that can be redrawn have an indicator in the upper righthand corner.
