Sock blanks are machine knit tubes created out of sock yarn to use as dyeing tools.  Frequently these blanks are knit with two strands of sock yarn together so when you dye your blank in any pattern you will be able to get matching socks.  I'm not a big sock knitter, so I decided to create some of my own blanks using a 
hand crank knitting machine
.  Today I'm going to demonstrate handpainting this blank into self striping yarn (a long rainbow gradient) with KoolAid using 100g of KnitPick palette yarn in a blank.  (
You can read more about my knitting machine here.)
 
 
The Plan, Dissolve 1 packs of 6 KoolAid Colors into 1/3 cup of water each. We used Cherry, Orange, Lemonade, Lemon-Lime, Ice Blue Raspberry Lemonade and Grape.  Presoak Blank for 30 min.  Squeeze out excess water and hand paint large sections to get a long gradient.  This project was so beautiful that I ended up taking multiple pictures along the way.

The gradient didn't turn out perfectly.  There was some leaking of 
colors from where the reds and purple dye spilled out the ends, but 
overall we have a really successful asymmetric gradient.   The different
 sections of color are not evenly distributed, but this is something I 
knew from when I started filming the video.  I could have divided the 
blank into 6 equal sections first, and then scrunched up the middles 
rather than guesstimating as I did... however I think that this will 
still be a fun colorway so I don't mind!

| Ready to unwind! | 
When winding into a center pull ball, I'm realizing that the 
imperfections from the machine knitting (link to post) made it 
impossible to unwind easily.  Somehow these twists didn't easily resolve
 on their own, and I ended up cutting the yarn and making 
Russian joins and/or
 felted joins
 in multiple places.  (This would NOT be an issue with a commercial knit
 blank, so this is why I did not mention this in the video.)
