Because I wouldn't ask you to do anything I wouldn't do myself, I'll be doing an upcycling project during the Spring Challenge.
I started with an old alpaca jersey my daughter found at the Sally's. It was a hideous mangled object, oatmeal in colour and repulsively distorted and felted from being machine washed. It had a lace pattern around the bottom, no ribbing except on the neckband and apart from that was a very simple set-in-sleeve shape.
So first up, I decided to dismantle it into the future components of a waistcoat, hat and mitts. This would make it easier to dye evenly, I hoped.
I decided that since I had some nice thick-and-thin yarn in Nightfall, I would dye the jersey navy.
The biggest bonus of the dye treatment was that it further felted the fabric into a dense, luxurious silky knit with a lovely surface sheen.
So that was day one - at the end I had several pieces of beautiful,densely felted navy alpaca knit fabric.
