Soo sorry to hear you're upset about storing your fabric. GLAD to hear you have a little one that NEEDS you...she deserves you.
Questions though...I don't remember if you mentioned how long you plan to put fabric in storage? How much will you have to pay for it to be stored? Will you LOVE the fabric you paid to store when you take it out? Do you think it will be all yucky and smelly? Can you sell some 'somewhere' and make a few extra dollars? I like the idea of putting a container at a friends house.
Keep what you LOVE and find a place for it (love the idea of raising the bed or going up higher in the room...what about closet floors?). When you get breaks from motherhood, work on one small project at a time. The time will come soon enough that the kids have moved out and it's just you and the hubby!
Good Luck and (((((HUGS))))))
