One project that I recently finished is the In a Pear Tree baby Cardigan. The pattern is available as a free Ravelry download, and was designed by the Barbarian Horde.
I knit it using some yarn that I had recycled and dyed... thinking that since the yarn had both blue and pink in it, it might somehow be gender neutral. (I knit this up before I knew if I was expecting boys or girls).
But yeah... it totally looks like a girl's sweater.
So I thought, why not see if I can overdye it blue?
So I got out my handy dandy dye pot, and dug out all of my blue food colouring and got to work.
Oh I filmed it too!
And I have to say, I think I like the result.
It came out maybe a little darker than I wanted, but that's ok, I still like it. Now I'm off to go knit a second one, and overdye it differently (because twins shouldn't match perfectly, right?)
Let me know if you've had any successful overdyeing experiments in the comments below!
