I'm in a similar boat. And, wow, it is so overwhelming to look into my sewing space with all of its stuff. We hope to put our house on the market in mid-May and are plugging away at sorting, purging and packing. I'll have a mini sewing setup in Maine and the second bedroom in Florida when all is said and done (and this house is sold). The house next door just went on the market this week and we've seen three sets of people there already today so that's encouraging. (It's a ranch with only one bath and we have a two story cape with two baths).
Next trip down to FL, I'm packing fabric and then again in July. Not so much because I need to, really, just to feel like I'm making some progress in that area. I have a featherweight there already and one to keep in Maine and will do the same with two regular sewing machines.
Good luck to you, Rhonda Lee, and all the rest of you. It is very encouraging to know that others are dealing with this, as well!
