The process is easy. Gather your sweaters a few at a time (we have a lot of sweaters around here as you can imagine!) and put them in your favorite sweater carrying box ;). Mine is a cherry box. I just love the graphic on it.
Because of the size of my drying space, I usually do batches of three sweater or two shawls. Please use common sense; don't mix light-colored garments with those that might release some dye. Follow my Handwashing Guide or use your own favorite method. Once completely dry I store them for next fall. My studio has a small linen closet that I use as the "sweater pantry", but any out-of-the-way shelf or drawer will do as well.
Nothing is nicer than pulling out a sweet fresh sweater for the first autumn breeze. Hand washing your knitted items before storage will help prevent insect damage by removing the major moth attractants, unwashed, well-worn wool. For extra insurance and if you like the smell, a bar of soap placed on the shelf close by the stored garments is said to detract the buggies. I'm not swearing by that, but it might be worth a try. Dried lavender and cedar are the more traditional choices. In my pantry the sign reads "no moth balls, please". What kills them probably isn't good for us either.
