Marniesews Sewfine the retail shop has been inseveral places in Watford, and was run by Malcolm, last place before Malcolm retired was in Queen's Road, so just past the underpass that separated the two parts of the old Harlequin. Malcolm also had shops in Egdware and Uxbridge. Steve was Malcolm's mechanic for many years. So when Malcolm retired, Steve took over the Sewfine name and moved himself to North Watford to cheaper premises and only sells machines and does servicing - nothing else - all the fabrics, haberdashery, knitting machines and yarn, various courses which were held up above the shop have long gone which is a shame.
However we are lucky in that Steve is an excellent mechanic, he really knows his machines inside out and is rated very highly by the Bernina people in London. It really would be worth your making a trip to see him, he is very close to the A41 so you do not have to actually go into North Watford shopping area, as he is in a complex called The Wenta Business Park.
