LOL....I opened this thread to answer the title question. YES, you can have too many pin cushions. Two is too many. I like my pins in a tin, not a cushion. I do keep one beside the sewing machine after knocking the tin off too many times. I really don't like pin cushions. They make me nervous.
Looks like some of you are collecting my share for me. Keep up the good work! I have three or four extras right now I am trying to rehome.
