Named because the spiral is rather bright - like the sun on a fine day.

Today's Gratitude Item: The beautiful scarves / sashes that one of my dancers made for our upcoming performance. We chose the fabric together (it's silky, shiny and very pretty) and she then went home and spent ages at her sewing machine. The results are magnificent and I'm looking most forward to wearing mine. Thanks Carolyn. You are the best!
