Sometimes we end up with a skein that isn't quite right. Maybe it only weighs 80g when its supposed to weigh 100g, or the color isn't exactly what we were going for (like that time I accidentally used blue instead of purple dye in a batch of Mystic Purple...). Or maybe the skein has a few knots in it. Often the yarn is perfectly usable, it just can't be sold as one of our regular skeins. So it ends up in the Serendipity box and these "irregular" skeins can be purchased at a discount price on our etsy shop.
I just added a bunch of new skeins to the listings and will be adding more over the next week. And remember, these great deals will not be repeated. So if you see something you like, buy it before someone else does!
