Sewing isn't something that Buffy has ever done. In fact, sewing is probably something that people who know her would attempt to keep her from. There are far too many chances for disaster. Her mother had sewn buttons back on and things like that when she was a kid, but once her mother died, any mending that had to be done was done by a dry cleaner or by Willow's magic. Giles had sewn a button onto her coat one time. In short, she had no experience with sewing. Buffy has many physical skills, but there are many, many things she can't do.

She wrinkles her nose at Clint's discovery of the stains. "They really have to get the bot processing factory back up." Because she's assuming that there are bots for this and they're just broken down. "Okay so...club soda?" She heard one time that it was good for stains. "Do we even have club soda here," she says surveying their stock of chemicals and cleaners.
