Oopsie skeins are OOAK (One of a Kind) skeins that generally turned out a bit different from how I intended. There may be a stray speckle, white spot, or often they are just not the color I was going for. The yarn base may also be a base that I have discontinued. The yarn is perfectly good and ready to be worked up in any project! They are all sold as the sets that are shown and are final sale.
