All this copyright stuff can have your head swimming for sure. Coloring books and printable coloring pages from the internet seem to be acceptable as a form of art activity for the children. Disney is huge on this as well as other making the likeness of the images. Cars are seemingly treated the same way. Most of the scrolling stuff don't show the protected logos . I think the biggest thing is when someone claims credit for the design of the logo as part of the art. The other part is mass production, scrolling pieces for friends, family etc. I feel it is safe. I do it, a lot for our local sports teams and never had an issue, but I don't mass produce them for sale. Really I think on low volume nothing will be an issue. Just don't post patterns as I believe this could get ugly fast for anyone.
