the faculty or phenomenon of finding valuable or agreeable things not sought for; a happy accident, a blessing
Sometimes skeins in the dye pots things don't turn out quite as expected. The dye weight is off, mineral content in the well water is different, an errant turquoise dye particle was in the pan. Or sometimes we just want to experiment. These skeins are the result. There's nothing wrong with these skeins, they're just not what was expected. They are labeled so you can find the ones from the same batch, but many are not repeatable, and will forever remain One of A Kind (OOAK), so if you like it, better get it. Every now and then a Serendipity color will be named and added to the regular lineup. It's hard to predict.
