I did not discover my passion for knitting until I was in my late 60's and retired from my software development career. Once I caught the knitting bug, I could not learn enough! I was very fortunate to learn of the TKGA Master Hand Knitters certification (https://tkga.org). I signed up immediately and worked on it every day for two years and became certified in 2017. It absolutely changed my life in retirement.
In fact, I no longer consider myself retired. I am now a professional Knitwear Designer and the developer of Phrancko.com, which combines the two vocational passions of my life, knitting and software development.
