In an introductory note to this chapter, the Kitzur Shulchan Aruch writes that most Jews are already familiar with the prohibited labors of Shabbos and that he is only addressing common situations with which people may not be familiar. Clearly, the laws of Shabbos constitute an area requiring much greater study than this email alone will allow.
80:91 There are many different opinions when it comes to folding clothes so it’s best to avoid the situation altogether. (One may fold garments not on the existing creases, though it’s preferable not even to do this – OC 302:3 and Mishnah Brurah 302:19.)
80:92 If a garment catches fire, one may pour liquids other than water on the garment so that when the fire reaches the wet spot, it will go out. We may not pour liquid directly on the burning part, nor may we pour water on the garment.
