Playing with acid dyes

The acid in the title is vinegar, så nothing dangerous - I promise. 

Last weekend, when my mom visited, we played with some dye and yarn - and ended up with this bowl of spaghetti (ready to hang and dry). Grey and black for specific projects (why buy a specific colour of yarn when you can dye it yourself?), and the rest is a great mixture of pumpkin orange, emerald green, burgundry purple/pink and a brilliant blue. 

I thought maybe I ought to knit up a couple of Christmas balls in the handdyed yarn, just to show off the colours.. but I have a couple of swaps I need to sew for first.
