Whirling Hexagons

Here's a pattern I'd never seen before having this quilt come in for repairs.  And green is my favorite color.  So I had a good time working on it!

Barbara Brackman's book shows it with two names - Whirling Hexagons and Texas Trellis. The block has a really simple geometry that makes a vibrant overall pattern.  It might work well as a scrap quilt, too.
