Creative Seasons?

With the official arrival of winter last week and the realization that I have not accomplished much on my pile of art quilt projects this year, I have been thinking about my work habits.  I definitely notice that I do not sit and sew as much in the spring and summer, as I enjoy being outside and love to tend my vegetable garden.  I have made adjustments though; I've discovered that sitting on the porch and sewing is delightful, and there is the bonus of letting fabric and thread scraps fall where they may, to be carried off by the wind. 

Now that it is bitter cold and daylight hours are short, I am more inclined to stay in one corner of the house and work on something creative.  In the summer, I look for more things to do that get me outside, or at least out of the house: fabric dyeing, auctions and flea markets (looking for sewing machines and anything I can re-purpose it to art), and gathering ideas from my adventures.  For me, the ideas never cease.  How does your creative energy ebb and flow throughout the year?  Do you have certain times of year for specific techniques or stages of a project?
