About a week ago, I went to a couple local thrift stores and bought some clothing. Not too unusual, right? But I didn't really look at size, color, or general style of the items I bought. I only bought knit fabrics with a particular type of seam, and with what I deemed a "good" fiber content.
I found four pieces of clothing (two cardigans, one sweater, and a dress) that fit my criteria. I was hoping to find more, but four turned out to be quite enough!
You see, yarn is quite expensive. I knit quite a bit, and that requires a sizeable stash of yarn. When the amount of quality yarn it takes to knit a hat hits about $25, the amount of yarn I would need to make a shawl or sweater makes me uneasy (hint: easily over $100).
