Definitely nature, for me. I have "color ideas" for two quilts: one to celebrate trips my family used to take to Florida. It's the color of the waves, backlit by the son, that are stuck in my mind for this one. The other idea came to me while driving to church a couple of weeks ago, where there was a little snow and a blue/cloudy sky, and it was so cold that the dried grasses leftover from summer were all coated with frost that paled out their colors.
Dreaming is free... and whether I ever make these quilts, I can enjoy them in my mind.
