I've frogged 2 sweaters using this yarn so far. I'm hoping that this will actually be the one that I'm going to continue with enough to finish. The pattern is Featherweight Cardigan by Hannah Fettig. You can download it from Ravelry for a fee. I think it will be worth it. I think I'm going to make it longer though. It's knit on circular needles back and forth. No seaming. The yarn is Berroco Alpaca Light. I say ,"Third time is the charm".
