Okay ladies, I want to find the absolute BEST yarn for Aran sweaters. I asked my mom what she would want if I were to knit her something, and she wants a classic, natural colored, Aran sweater. I asked if it was ok to be dry clean only, or hand wash only, and she said yes. So now I want the softest, nicest yarn for the sweater. I'm thinking that Merino won't hold its shape well enough, but am not sure what will work the best. My mom is hunting for a pattern for the 'perfect' sweater, and I want to get an idea how much the yarn will cost, so I can make her a surprise for Christmas. Hit me with the ideas ladies. TIA!
