icy conditions

Everything was coated in ice this morning. This is the first winter weather we have had this season – up until now it has been unusually mild. The garden seems to glimmer under the ice layer, everything looks cuddled and safe, but also fragile and exposed at the same time. During my wanderings I discovered all these oak leaves on the ground, much darker in color than the others. They look oxidized, almost blue. Immediately I start thinking about the dye pot - what color will they give in that condition? I have so much on my plate. Can I fit in a play date with the cauldron?
