I'm about to have possibly 6-7 total pins in the next month. I've always kept the pins at least 5" apart, which leaves a little bit of a gap between each pin. I've noticed some other pinsiders have their pins almost touching. I've always been paranoid about accidentally nudging a pin too hard and hitting into another pin even though it's on carpet, thus doesn't slide at all. Eventually, if I want all of the pins to fit on the same wall, I'd have to move them fairly close to each other. Just curious how others space out their pins and if there has ever really been an issue having the pins together with very little spacing?
