What do babies, bikers and brides have in common? They all can get apparel personalized at Keep U-N Stitches in Casa Linda. Owner Gina Maria Volpe, in business since 1997, and her two assistants can stitch everything from ladybug designs on babies' bibs and diaper covers to bikers' and rock bands' "sometimes unmentionable" logos on their shirts and caps. They'll also add special motifs to bridal lingerie. Hey, they'll even add fancy stitchery to coffin linings. Now that's going underground for business.
