JJM Jewelry - This shop sells jewellery supplies, clasps, beads, findings as well as handmade jewellery. They also have a sale on at the moment. I will definitely have to have a good look through this shop as some of the beads look brilliant.
Blue Girl Jewelry - Hand crafted and wire wrapped Jewellery at a very reasonable price.
Sassa Lynne - This Etsy seller is another British seller and sells hand dyed yarns and threads as well as hand dyed scarves and other fiber art supplies. The items in this shop are truly unique, being created from random dye pots, so would be a perfect investment for someone making individual textile based art & crafts.
I have had a look on some of the other shops on Etsy, but will pick 5 tomorrow to add to my favourites and then 5 next week and so on...
