Knit Picks used to sell a variety of colors of their "Decadence" line (100% alpaca in bulky weight for $6 a 121 yard hank), but their recent catalog shows only three colors.

Does anybody know of a 100% alpaca bulky weight yarn that's comparably priced from another source, or maybe even an affordable 100% alpaca in a worsted weight that I can double strand? Why would they cut this line down to only three colors???
