Thanks, barny..... We should be good with "moisture" issue. The farm next door (a few acres away) offered her guest bedroom to spread them out on a bed if I wanted...which was so sweet of her. I'll be checking them regularly and will be removing the cardboard when I arrive and hanging heirloom quilts in RV closet. Our workshop is a steel building heavily insulated walls and ceiling. I think the hottest it got last summer inside was 78.. I think I covered all the bases and have back-up plans. Fingers crossed because I have fretted over this enough..lol...
