At that time, the best thread at my LQS was Mettler and I used it exclusively for years. And then, I bought a new machine. I bought a Bernina. It was the most expensive machine purchase I had ever made. I told myself and my husband that this was the last machine I would ever own (hopefully) and I intended to take great care of it.
Then, in 2010 I discovered blog land and began following many blogs and eventually began my own blog here. I entered a giveaway on Lily's Quilts blog in October of 2011 and won a 48 spool suitcase of Aurifil threads. You can read about that here.
A couple of months ago I tried to use another brand of thread in my Bernina. It did not go well. I think she is just as hooked on this thread as I am.
