Always enjoy seeing libraries using discarded books to create art, purses, or furniture! Go University of Warmia and Mazury of Olsztyn, Poland (and a Wesolych Swiat Bozego Narodzenia – a shout out to my ancestors in Poland!) for their lovely giant Christmas tree created from books. See the writeup in American Libraries or visit their website for more info and videos. Check out more trees made from books from my past blog posts too!
