There are lots of fabric shops around Berwick street - but this one is my favourite, They carry a wonderful assortment of fabrics for garments and upholstery, faux leather and faux fur and their specialty high-end fabrics are gorgeous. As Matt D. said it's somewhere between a fabric boutique and warehouse since they do carry basics but their specialty fabrics are wonderful.
Swatches are available (either free or a nominal fee depending on the price tag of the fabric) and I always go into the basement to dig around the remnants bins. I usually find some really great deals in there and if you're buying a lot of remnants you can usually bargain a little bit.
The staff are friendly, helpful and professional - they once sent me to another store because they didn't have what I was looking for! Most places would just shrug and say "Sorry, we don't have it" aka "You're shit outta luck, don't bother me" but here they take the time to chat with you and help you find what you need. read more
