Have needle, will travel. A certified nursing assistant by training, Millie Ferguson charges $25 an hour to keep you in stitches. She'll bring her rolling sewing machine to your home or office to make alterations, mend, hem or replace buttons. And Ferguson's not reluctant to tackle big jobs, either, like making banners for corporate shindigs or creating outfits for those who can't get out to shop. For the past five years, she's proved that a stitch in time...beats coming unraveled.
