I have this goal, to finish a UFO! there I said it, I have a UFO, I actually have more than one, but this one I still really like and it has few or no mistakes.
The biggest mistake I made was not having enough yarn for the sweater. I started this sweater around 2001 and must have put it aside thinking I had misplaced the remainder of the yarn. When I pulled it out last year to finish it, I made the discovery that there was no more yarn, it had all been used in the progress.
Thankfully I had become a member of Ravelry, an online knitting community. I posted that I was looking for this really old yarn in apricot color. I didn't get just one, but two people who had the yarn and in the right color. I forgot to mention that I had purchased the yarn some 10 years earlier and bought it on sale, so it was probably no longer being made when I got it. Back to the story, I made a simple donation and the yarn was sent to me. While the yarn that was sent was a different dye lot it was pretty close and I had some of the original yarn to blend the knitting.
The button band with some buttons that I found at Britex in San Francisco, they are lucite from France... I thought it was perfect as the patten is one from the French yarn company (sadly no longer with us) Pinguoin. I have knit a couple of items that I found in their pattern books, I love the style and the patterns for the most part were well written and frankly if you knit classics, you can weare the garment for decades or until you wear them out...
