Q: [header] How to care for sweaters [title] Fold your sweaters. [step] Don't ever hang them because hanging sweaters will result in a larger sweater than the last time you put it on, or a misshapen profile. [title] Remove pills from your sweaters regularly to keep them looking presentable. <sep> (A) [step] A small piece of paper from a package containing a piece of letterhead will be sufficient for this purpose. [title] Make sure to download from a reliable website. (B) [step] Pilling is caused by rubbing during wear and is more apparent around the elbows, under the armpits and on sleeves but can occur anywhere on the sweater. Purchase a hand-held depiller or a small electric shaver made for depilling. (C) [step] Do not keep a leftover pill from a pharmacy or at home because you may throw the disc out the window when you throw the next one. [substeps] Be sure you throw away any empty bottles or other containers of pills that break during the trip. (D) [step] Your calendar gives you a good idea how often and what to avoid, so it's important to keep track of what times you're spending on your sweaters each day. Try to take your medication away every 3-5 days.
