Only my best quilting friends can borrow my quilting stuff. We feel like our sewing rooms are all our sewing rooms. No one else gets to borrow my tools to take out of my home. What chaps me is at a class or workshop, I buy the ruler or tool recommended for the class and someone will ask to borrow it for a minute because they didn't buy one. I can say NO in a second.
I got over being nice a long time ago to freeloaders.
