First get a layout diagram of the unit. Put it on grid paper (measure 2x) See where your furniture will fit. Measure how much sq. footage it will take up. such as length and width of space as you have it now. Sofa, recliners, end tables. After all that decide what stays and goes with family also. Then have a moving sale and let your guild (if you're in one)and other "crafters" know. If you're on FAcebook or one of your kids or GKids are let thempost it for you only the day before. You may want them to post also "ABSOLUTELY NO EARLY BIRDS". My sister had a garage sale to begin at 8:00 a.m. and "g-salers" were showing up at 7:00 a.m. Anything left over you can donate.
