书皮

书 = 丨 + ㇆ + 丶 : Sheldon Shrimp (shu) is enjoying a good book (书) in front of the space station (Ø1). Because he is lazy, he built a thingy to hold the pages in place with a dinosaur bone (丨) and two plows (㇆). He is laying very comfortable on a petal (丶) serving as sofa.

皮 = ㇖ + 丿 + 丨 + 又 : Mnemonic symbol: a cow's hide.

皮 = ㇖ + 丿 + 丨 + 又 : Just inside the entrance of the space station Pocahontas destroys her cow's hide with a sickle because she decided to go vegan. Instead of leather she'll wear a banana peel as coat, boxing gloves as shoes and a big dinosaur bone as long hat.

皮 = ㇖ + 丿 + 丨 + 又 : New mnemonic symbol, since I also use the cow's hide for 革: leather shoes.
