I had to move and downsize as well. I bought totes at Walmart. Just don't make the totes too large because fabric is really really heavy when the tote is full. I organized mine into colours and labeled them well. The other quilting items I used packing boxes. I really advise that you label your boxes well. Tell yourself what's inside. It really will make your life much easier. This is my 3 rd move in 7 yrs. I hate moving but I am getting good at it!
