2.42

（佛言：「為身、為衣、為臥具，故制畜之。」長周四尺，廣三尺。更增半搩手者，《律本》、《善見》云：「令於縷際外增之。」《十誦》云：「新者二重，故者四重。」《僧祇》云：「不得輒爾持故物作，及屈頭、縮量、水濕量。若乾大者，犯墮，受用犯小罪，此是隨坐衣，不得淨施及取薪草、盛物、雜用。應中牒左肩上而行，至坐處，取坐之。若置本處，當中掩之。欲坐，徐舒，先手按，後乃坐。」《十誦》云：「不應受單者，離宿，突吉羅。」《五分》云：「須揲四角，不揲則已。」《摩得勒伽》云：「若離宿，不須捨。」律、論制受，闕文，應義加云：）

One should fold it across the left shoulder when walking; arriving at the sitting place, take it and sit on it. If placing it in its original spot, fold it in the middle.
