One Seam Flying Geese!

Yes, the wonder of it all!  Flying geese blocks made with just one seam as seen in The LookBook published by Art Gallery Fabric Studio.  Go there, page 20.  Sew fun.

With two 2 1/2" blocks (the background) and one 4 1/2" x 2 1/2" block (the center) stacked and with one seam.....you've got a 2 1/2" x 4 1/2" goose that flies. 

In this order: 

2 1/2" block face UP
4 1/2" x 2 1/2" rectangle face DOWN then folded back over on itself so raw edges are aligned to the left.  Yes, you'll see 1/4" of the background fabric. 
2 1/2" block face DOWN

Keep aligned  and take to sewing machine and stitch across the top.  Manipulate the center and press.  Sew fun, so easy.

Here's my first block using this technique.  And then, there was two!
