Berrocco yarns has a quick photo tutorial on how to wet block knitted pieces. Why re-invent the wheel? So, I have posted the link. I find that a total immersion of the knit into water evens out the stitches, gets rid of the dust and hand oils from the knitting and of course the chemicals used in the spinning process at the mill. I place my items on a styrofoam insulation board to air dry.
