There is a stall at our local market that sells off magazine back issues. Just the last issue as the new ones have just come out, but I got a copy of a magazine called Beads&Beyond for only a pound which had loads of stockists details in it, and plenty of ideas/howto stuff. I may buy it again. I'm planning to go to the Hobbycrafts show at the NEC (Birmingham) in November and will look there, and if I can't find what I want, I'll follow up these stockists in the mag.
I don't know how good these are but some more for you:
