I have a quilt that I started when I saw the Hale-Bopp comet in the late 80's. I got all the fabrics, looking frantically for months for the "right" starry material (since the scene is of the Golden Gate Bridge with the comet in the background in early evening). I found the "right" brown/gold for the bridge, and got everything cut out and placed. Then - Nothing! I couldn't get past the embroidery and piecing, even though it's all there.
It sits in a bag, taunting me to get going on it. It is the only quilt I have that I haven't taken the time to finish of mine. My children helped me get it laid out and still ask me when I'm going to get it finished. ONE OF THESE DAYS!
