I work for a non profit that helps kids with cancer. I di the summer camp crafts( and now holiday party) for the kids every year and I use a lot of scrapbook type supplies. There is also an area on the oncology unit where they have scrapbook therapy or art for the children. In there (or the parents who are there awaiting treatment for their little one) When I get donations thru the charity (and not the hospital) I usually go thru and send the things that are better for teens/adults to the hospital and put the other back for camp.
When I go to big crops there are several swap tables. You put stuff in, take our what you want. This last one covered about 4 tables full of stuff! I went home with a ton of papers and things that were new to me.
After everyone took what they wanted there were still stacks and stacks of stuff. The organizers of the crop took it to a children's hospital I think or somewhere that likes to get the leftover items.
Art teachers in schools are generally VERY appreciative of supplies. When I cleaned out my scraproom/craftroom, I took excess stuff to the school and they were thrilled to get it. My dd's art teacher this year has actually sent out a request for sb supplies...I think they are making art journals from old books.
I used to be a member of a local scrap group that was a charity. we had some different places we sent extra supplies....to make cards for veterans, we had a member who had a group of teenage mothers who had no money so she would help them scrap their babies, nursing homes so the patients can make cards, another huge one was the local childrens hospital...we actually made a room for the parents of very ill children to work on crafts while their child was in the hospital. They made up prepacked kits to make cards. we donated lots of extras for that.
