Quilting has led me to develop a new found respect for something that perhaps doesn't get a whole lot of respect - the triangle. It's an amazing little shape.
Turn a couple triangles this way and you have a square.
Turn a couple triangles that way and you have a diamond.
Spin them around a bit and behold, you have a pinwheel block (or lots of pinwheel blocks)
And that's how the triangles will stay.
I'm in the midst of making a pinwheel quilt...finished size yet to be determined. Not a whole lot of planning went into this quilt. I'm going to see how many blocks I get from the 7 fat quarters that I had, see what size sashing looks best with the blocks and go from there. Of course, I could have calculated this all beforehand but that would have required a little thing that I like to call effort...and that is something that is in short supply around here nowadays.
