It's important to make the right choice between hanging and folding for storage. It's generally very simple to make that determination. Sturdy tight weaves do just fine on a hanger, and require very little maintenance when it is time to reactivate them. Most knits, especially the looser and thinner ones, should be folded (using acid free tissue to soften the folds) to prevent distortion of the shape. A beautiful knit can become horribly distorted if stored carelessly. - Updated: March 29, 2006
