Knitting and sewing garments produces scraps, there is just no getting around it. It is tempting to point at big companies that produce clothing and complain about their cutting room floor scraps, but anyone who makes their own clothes also knows how hard this problem is to avoid.
I made a poncho!
I knit this poncho using wool that I purchased with no pattern and no plan. This may not sound like a big deal if you have not knit before, but buying yarn with no plan usually just leads to a closet full of pretty yarn, rather than a closet full of pretty sweaters.
