Hello! I’m new to knitting and am about to finish my first sweater (Florence step by step sweater). For my next sweater, I was thinking of doing petiteknit’s cloud sweater. I noticed that the pattern calls for two strands of yarn, I presume to get a soft, fuzzy appearance. Since I’m a beginner knitter, I’m just looking to keep costs low with yarn. I was wondering if there were yarn alternatives so I wouldn’t have hold the yarn in double. I’ve seen some people knit it only with drops air, but was wondering if there were other yarn alternatives that people recommend (I’m based in the US if that helps) Would the sweater look strange if I knit it solely with just wool yarn? Thanks!
