Here in St. Louis, MO you can find the Staedtler erasers at Art Mart. I bet Dick Blick Art Supply would also have them. I kind of doubt that Hobby Lobby carries them. Any better quality art supply store or drafting supply store will have them.
Thanks Sue so much for this month's video. I have been very frustrated trying to draw feathers. I was beginning to think I would not be able to draw any. After watching you draw your feathers, I was able to draw decent looking feathers.(lightbulb moment)Woo Hoo,TQS rocks. Thanks,DixieH
