It's a real thing! Do a search on funny t-shirts for quilters.
I have a nice rainbow sewing machine "Quilting is my Therapy" (I chose that over "I quilt because choking people is frowned upon" even though they mean basically the same thing...) and the other one looks all pretty and flowery but says "It's ok if you think sewing is stupid, it's sort of a smart people hobby".
And today I got a flier that does give me a free pass to the expo thing. I know the ladies in my quilting group are going to go, and I've been thinking about Kai scissors ever since last year...
It's a good thing I'm in the Fabric moratorium and not the thread, t-shirts and notions moratorium!
