I started with this Oatmeal colour of Berocco Vintage. It was a colour I ordered online and it wasn’t at all what I’d hoped it would be. Every other oatmeal from a yarn company I’d seen looked far paler (like oats) while this was a weirdly warm beige in person. It’s an acrylic wool blend, and I wasn’t sure how well it would overdye. But I got the itch and threw it in with some KoolAid over lunch yesterday.
First I soaked it, then skeined it up and microwaved it with 2 packages of cherry.
It looked like it had gone all the way through while it was cooking, but I was totally fooled and the insides were still the original colour.
Once it was cool, I put two slip knots in it and tossed it in with a package of orange.
Unfortunately, I didn’t get a picture of that result. I had a great mix of cherry and orange, but enough of the original survived and just didn’t look right with the tones of the dye. So I opened it up and put in a package of cherry to give the whole thing a unifying colour. In retrospect I ought to have tried a half package, since I lost the orange except as an undertone that still looks lovely.
It turned out a beautiful, soft, autumnal colour. I’m browsing patterns for about 200m (220 yds) of worsted weight if you have any suggestions.

Not sure what you should make, but I love that you described the colours through the flavour names of the koolaid! The results are pretty too 🙂
