You know you're addicted to sewing when...
...you decide to drive 11 hours each way to a 4-day work event instead of flying like everyone else, because you don't trust the airlines not to smash your machine and you can't imagine spending 3 nights in a hotel without one.
...you have a week-long Hawaii vacation in the works, and one of the things on your "to-do" list is to call around sewing machine dealers on the island and find out if you can rent a sewing machine for a week.
...your husband is out of town for a week, and missing him is balanced by gleefully realizing nobody will stop you from spending your entire evening in the sewing room, every evening, all week long.
