We're in the process of getting ready for listing right now (t minus 10 days), and I packed the entire sewing room except for a couple of things. I kept my main sewing machine out and tucked it in our walk-in closet, I have my AccuQuilt Studio and my small dies tucked under my bed because I have a not-for-profit organization I have already committed to cutting stuff out for, and I have two small "kits" that I made and have tucked away on a shelf in my linen closet that is pretty much empty of everything else.
If you do go the kit route, sit and think through each stage of the project so you don't end up finding out that you've packed something that you still need. I made sure I had the matching thread, bobbins, pins, a pair of sewing scissors, a small board to press on, my iron, the binding, and the necessary batting.
