Thanks, ladies, I needed this. I do tend to do things to one extreme or the other, so I can see how Dec did seem like a good idea at one point. I think I did really underestimate how much this hobby means to me.
1 item a month, I think I can do. First things first: I need to return the items that did not work out! I kind of forgot about them during my vacation. The wedge shoes are on their way for April, and once I return my jeans I will have a vacancy for March. I don't remember when I started this whole thing, but I won't worry about what happened in Jan and Feb. Onward and upward.
I WILL count thrifted stuff in this, since my goals are more about space and efficiency than money - I hope this will help me be more choosey re: my swap meet items. I also want to keep it to one-in-two out for a while, but I'll do the purge first, and build up "credit" based on how much room I want to have.
