[If one] made an “ispilanis” plaster, whether of cloth or of leather, it is tahor. R’ Yose says: [If it is] of leather, it is tahor. [If he made] a “milugma” plaster, [if it is] of cloth, it is tahor; [but if it is] of leather, it is tamei. Rabban Shimon ben Gamliel says: Even [if it is made] of cloth, it is tamei, since it can be shaken off.
