Ok, this may have been asked before but I couldn't find it!

I know that media mail rules say you can't send printed material with advertising in it - which is why you can't use it for magazines.  But what if you used a page from a magazine to wrap the book (inner page, not outer)?  I'd love to use pages from my junk mail (pottery barn, container store, etc.) but I'd hate to have something returned to me because of my wrapping!

Should I just toss those or are they ok to use?

I can think of no reason why you can't do it Rhonda. 

Thanks Steve!

I wouldn't use magazine print to wrap books because the ink could transfer to the book.  You could get stains on the pages...

That's what the waterproofing layer's for. :->

Yeah well...duh...silly me...
