I decided to use up some leftover yarn. It wasn't the right colour. So I changed it. Keep an eye out for more news on hot cocoa in blogtoberfest posts to come.
Edited for Susuan:
I use Gaywool Dyes, and a couple of Landape dyes I bought ages ago in a sample pack. This method shown here is the kettle dyeing method, which I use for semisolids only as I have a fear of ugly colours forming when they mix (or perhaps I need more practice :P). This is a fairly easy method, you boil up the wool from cold, turn it down to a simmer and pour on some dye solution in random spots. Don't stir it unless you want even colour. And don't turn it for abou 10 mins as the dye will mostly take in the first 5 mins. Simmer gently for half an hour, rinse, wash, dry and reskein. Enjoy!
