Hi<br/><br/>Are these natural expressions?<br/><br/><b>He doesn't know how to peel potatoes thin.</b><br/><br/>Or <br/><br/><b>Don't peel the cucumber so thick.</b><br/><br/><i>[The intended meaning is: while removing the skin, he also wastes a lot of potato which goes away with the skin.]</i><br/><br/>Thanks,<br/><br/>Tom
