This was something that was hard to find when my students needed it years ago. I still had quite a bit left. It is impossible to find in stores today.A mutual friend mentioned her friend up north was looking for some in orange. I had just about every color it was ever made in and was happy to pass all of it along for her many projects she uses it for.
Yes, she was thrilled to have just about every color to use on her projects.
Who knows what this is?
