I agree with you, because sometimes the art or the things that our grandparents did, we find them quite interesting, for example my grandfather painted waterfalls, mountains, birds, landscapes, etc. on vinyl records. And although I could not learn that wonderful technique of painting, if I keep and treasure their art.
O wow, really?? How wonderful... Can you post some photos of it on your blog, and then give me a link to it when you do? Because that's one really interesting art, and I never heard of it before.
