The vinegar is added to the dyebath to help with stabilizing the dye. And you need to know how much your yardage weighs to know how much dye to add. It needed to be heated at a simmer, stirring constantly for about 30 minutes. Because wool can shrink up quite a bit if immersed into hot water, you need to add the wool to the water at room temperature and then let it heat up. Then dilute the dye in boiling water separately, take your fabric out momentarily while you add the dye to the hot water.
After dyeing, I had just under two yards of wool- just enough for a great short jacket. I used McCalls pattern 6294 which had a triangular insert in the back. My dyed wool had some parts that were more variegated than others, and I decided to feature the most variegated piece in the triangular insert. The wool was quite fluid, so I interfaced all of the pieces to give it more body.
I love blues and greens, and feel that this is a modern mix of colors that is "me". I can wear the dress alone or with the jacket, and the jacket will be wearable with many other items in my wardrobe, as well.
