I have used quite a few Redwork Clipart and made regular designs from them, or appliqué. As long as the lines are closed it's easy. The current clipartoon freebies would need some improvising. You can always add colours in Paint or whatever graphics program you have, I just go ahead in Embird, even draw my own pictures using the outline tool and go from there.
Thanx so very much for your answer. I really did not want to do something that was not permitted. Thanx for clearing that up! I have seen a lot of RW designs that would make really cute fill designs. I really appreciate you. Huggs, Judy
