I am working with Colrain at this very moment, well, like 10 minutes ago, and it is lovely to work with. It is a 50% merino 50% tencel blend, an amazing yarn for the price.
If you are at $45 now, you definitely have to get up to $60 for the discount, which will take you back down to $48. You can get $15 of yarn for $3 more.
Colrain, of course, is for cooler weather, but I'm hoping to finish up this sweater real soon since spring here is pretty cool. I have a ball of Goshen, too, haven't knitted with it yet, but it feels a whole lot like the KP Shine yarns to me, at least doesn't feel any nicer. But haven't knitted with it yet.
WEBS has such an enormous inventory, it's hard to advise you. Are you looking for summer or winter yarns? Fingering, sport, dk, worsted, chunky? Silk, wool, cotton, rayon? Yarns for stitch definition, ribbon yarns with glitz? :shrug:
