My closet is 24 inches wide, so I know what it feels like to have limited closet space! As a result, I actually fold my knits and keep them in a dresser because my closet space really does have to be limited to items that can hang. I fold them in stacks based on categories so that when I open the dresser drawer, I can see what type of knit it is. Right now I have the following types of knits folded up: v-neck sweaters, cowl neck sweaters, cardigans, long sleeve cotton shirts, short sleeve shirts, graphic t-shirts, etc. Basically, I stack like items with each other. I am a visual person and I thought I would struggle with this, but it's actually been pretty easy. I look forward to what other people say on this thread because I'm always looking for new ideas!
