Yes! I got a Kool aid kit in the DIY kit swap round 9 from Lizzle! I've dyed with other dyes, but never any food dyes or Kool aid, so it was perfect

I got four kinds of Kool aid, Knit picks 100% merino yarn (so soft!), instructions and easter egg dyes too!
As usual I'm really bad at following instructions (it was for hand painting with Kool aid), because I decided I wanted self striping yarn, another thing I've never tried before. And it is intended for a pair of socks, or maybe mittens.
So I started with knitting a swatch. To see how much yarn was needed for a row. From there I decided how long I wanted my colour strips to be. I finally settled on 5-6 rows. And I started to re skein the skein.. To keep it from tangling to much later, I tied every loop in three places.

Four different colours, so four smaller loops. Since I only have three chairs, the fourth loop got wrapped around something else, and thus is a bit shorter than the others.
When the skeining was done I mixed up the kool aid. It smelled great! Especially the orange.. In the middle is strawberry, then orange, lemon lime (I think) and Jamaica.

Since I had two skeins I decided to put the two smaller loops in the middle, and then one in each jar. So both skeins got the same colour repeats. You see the white parts where the yarn continues to the other loop in the skein? I was afraid the colours would bleed into each other there. But as we shall see..

After about 30min in the jars in boiling water (nothing else than kool aid and water in them). I took a spoon and checked if all the dye had adsorbed. The water was absolutely clear. BUT the white parts between the jars was almost as white as from the beginning

The dye had been nice and stayed put in its jars.. Nothing else to do now than to take up the skeins, rinse them in the sink (I put cold water on the hot skeins, I tend to be careless like that

, but it didn't bleed at all) and then dry them.
After they had dried I re skeined them into one skein again.

A finished skein! And a yet-to-be-reskeined skein.

To see if my calculations had worked I had to knit a swatch.. It was so much fun to knit with these colours! The white parts I was afraid of is actually not very visible. They tend to be pink and blend in quite well with the other colours. The colours are a bit variegated since the yarn was crammed into jars and I didn't stir anything at all. But I like that. If I had wanted more solid colours I would have had bigger jars and stirred every now and then.

Now I just need to decide what to do with the yarn. Mittens or socks? Or if socks, what kind of socks? I've been thinking of Jaywalkers, they look good with self striping yarn. But I need to recalculate the pattern and I'm lazy
