Wikipedia:Ten things you may not know about images on Wikipedia suggests that Wikipedia is more cautious even than required by law to avoid such copyright violations, but through ``fair use`` can put things like album covers on articles about albums...not discographies, though—complicated. ) Coming from an academic background, I'm a little unclear on some of the ``fair use`` allowances for images per Wikipedia's purposes. Reading over Wikipedia:Non-free_content#Unacceptable_images, I fear that a drawing of seams copied from illustrations of seams in a book may be interpreted like #3, as it is a similar kind of usage. My caveats aside, the thing to do at this point is ask the people in the know. There are three places you could ask this question. I would start with Wikipedia talk:Non-free content, link your article for them & tell them what you're hoping to do. The page has active conversation, so you may get an informed response within a day. My general philosophy is that if you can ask at the specific policy page, you're more likely to get a response from people who deeply understand the guidelines. ) Other options include Wikipedia's Help Desk which is for new and experienced users alike and the village pump, which is the big general conversation point on Wikipedia for tricky questions. This is subdivided into five sections. I would ask that one at Wikipedia:Village pump (policy).   `
