Did you know the National Gallery of Art will send loan materials to your mailing address? The loan period ranges from 1-9 months and there are hundreds of resources from which to choose! This is a wonderful resource for Charlotte Mason and classical curriculums, as they emphasize art study. Of course, I think it’s a wonderful resource for every learner!
I have successfully borrowed from the NGA for our homeschool. The items arrived quickly and were easy to use. When we were finished, we shipped them back to the NGA. The only cost on our part was to pay media mail postage for returning the items to the National Gallery of Art.
We received a disc full of photos of artwork, and much to my delight, we also received a dozen or so prints of work (not all resources contain the same amount of materials).
