I was just putting away some sweaters that had air dried and this question came to me.

How many of you hang up your sweaters? Or you do store them folded (on a shelf or in a drawer)? For me, it depends on the type of sweater. For the light, fine knit cotton shells and sweaters from Land's End/LL Bean I have several of, I hang them. To save closet space, I put both shell and matching cardigan on the same hanger. When I hang to dry, I put them inside out, so the shoulder marks from the hangers don't show. Yes, I still need to get a drying rack.

I have two bulky, heavy cardigans that do get folded on a shelf in my closet.

I always end up with wrinkles when I fold my fine knit sweaters, which is why I hang them.
