This is a list of sites I’ve found I refer to constantly for both my knitting and vintage needs:
They sell a great range of very fine yarns which are ideal for fine knitting (particularly fair isle), plus some more unusual yarns such as bamboo, tencel and rayon.
Toft produce a wonderfully fine alpaca, some of the softest I’ve ever handled (and I’ve handled a lot)
Jamieson & Smith
Excellent quality Shetland Wool providers, good range of colours, particularly useful for vintage patterns calling for 2 and 3-ply yarns.
Produce a beautiful quality 4-ply silk/merino mix which says it all in the title: Scrumptious.
No need to preach to the converted, but if you haven’t come across this site, it’s an imperative for all knitaholics. Wonderful project planning section plus groups and forums, opportunities to learn and connect with other like-minded knitters.
A world of unusual and great-quality yarns at your fingertips. If you’re ever stuck for inspiration, have a browse through their well-organised site.
I Knit London
Great community website for knitters from the London-based shop. Watch out for events, classes and knitting groups.
Knit On The Net
Run by Susan Crawford, knitwear designer, vintage fashion lover and author of ‘A Stitch In Time: Vintage Patterns 1920-1949′. Great free patterns as well as handy tips and knitting news. Also writes a blog under the pseudonym ‘Just Call Me Ruby’.
Lovely site from the U.S. full of public domain 20th century reproductions – Fleisher’s, Bear Brand, Corticelli etc. Well worth a look, especially for the 1930s books. Will post internationally.
Freddies of Pinewood
Excellent value ’40s and ’50s repro clothing, highly recommend their dungarees.
