I dyed this wool this morning for an order. It's going to be a very bright pair of socks! I used my microwave to set the dye. I dyed the blue for the mittens in a coffee tin on the stove, but it wasn't quite big enough, so the dyeing was a bit uneven. An ice cream tub in the microwave worked better. The microwave is quicker too, which is an advantage when dyeing five different colours.
