I signed up for the Joanne's Fabric mailing list by hand in the store. Apparently they could not read my handwriting.
I got a coupon in the mail with "For Mather Seerlo" printed on it
My sister, Anna, saw it and said, you should hold onto that. I put it on my bulletin board and looked at it intermittently for the next year and a half or so.
The original coupon was made into a collage and is in the collection of Jordan Stein.
