Halcyon has always been a great source for yarns- especially in a yarn market that is catered towards knitters! Their full supply of warp/weft yarns from 5/2's cotton to 8/5's linen make it very easy for the modern weaver to order online. Being able to order it all in one, consistent place has been ideal. I highly recommend purchasing the "Yarn store in a box", it has already paid for itself with the number of times I have found the exact yarn I'm looking for!
