A lot will depend on what the gauge of the pattern you are intending to knit. If you are looking for a chunky weight yarn then maybe our elann.com Peruvian Highland Chunky would work. For an aran weight there is Filatura Di Crosa Zara Plus Mouline, or Debbie Bliss Cashmerino Astrakhan which is very soft, or maybe our elann.com Peruvian Sierra Aran. When it comes to a worsted weight you could look at elann.com Incense, or elann.com Peruvian Pure Alpaca. If you let me know the gauge needed for your pattern I would be able to narrow my search down for you.
Please let me know if I may be of further assistance.
