Hawke House Marine, Portsmouth, have a good reputation or I can recommend my stepdaughter's company, Pigbags.com, here in Hamble! They are an emerging company and appear to be doing a good job....
No reason at all why IKEA should not be a serious suggestion. SWMBO re-covered ours with 'end-of-roll' from BLENDWORTH FABRICS (manufacturer/supplier) which happens to be just up the road. Curriously, when we wanted cuitains for the house made of fabric from same place, it was cheaper to buy them ready-made from a mail-order supplier than to buy the material direct to make them!
The best place - Ann (?Anne) Rose Fabrics on the Isle of Sheppey. They sell to the caravan crowd so their prices are excellent. They also supplied the foam at less than I could get it trade.
I was chatting to someone who does boat interiors last night and she was talking about using canopy material . Doesnt stick to your legs in the summer and is water proof . Good idea i thought .
Yep, there's a lot to said for that. I made all our cockpit cushions from the same acylic material as I'd made the large cockpit canopy, covers and dodgers from.
It sews (on our old Singer) very easily and the cushions are comfortable, waterproof (well resistant!) and, again to an extent, UV resistant.
Happliy, we bought the high quality acylic cloth in southern Spain at a price far, far cheaper than the same stuff in the UK.
There are also some excellent outdoor fabrics that have recently come on the market, such as Extex. Although they are not completely waterprood, they have a much nicer feel and appearance than canvas, and are resistant to stains, UV and mold.
I had covers made for all my upholstery on the old boat in acrylic canvas. Ideal for everyday boats. ie those that get the odd drop of water below, ones where the crew have to wear oilskins.
Oh, and you can chuck them in the washing machine too. Just have them made with velcro rather than thoise crummy zips that always corrode.
