I went to the fabric store to buy buttons, and came out with yarn. That happens to me a lot. What can I say? It was on sale.
Because I buy so much yarn - a skein here and a skein there - and because I make things to sell, I need to keep track of what I have and what I use. I thought I'd share my system here in case you need to organize your yarn, too.
Each skein is labeled with an accession number - the year and then a number. The two skeins I just bought are 2016.4 and 2016.5. Only 5 skeins of yarn so far this year - I must be falling behind! Details about the skeins are logged in a journal. I used to keep the log in Excel, but have found it's easier for me to do it by hand. Go figure.
I also enter the yarn info on a business-sized card and put that, with a sample of the yarn in plastic sleeve in a note book. The notebook is organized by which of the many bins of yarns that I have - roughly by fiber type. This way, when I'm thinking about a project I don't have to pull out the bins first, I start with the book.
