I have found the serger works well for simple patchwork for clothing or other applications where I don't want to line it - like some tablecloths, or a big duvet cover I did for a lady last year. She wanted patchwork on both sides but didn't want it quilted. A serger made it much more durable and washable (and it was FASTER!).
Little girls' patchwork twirly skirts are selling well on ebay, and those are good to make with the serger, too.
