Three right angled triangles are all that is needed to create one of these Flying Geese units (or patches.) The largest triangle piece is considered to be the "geese" piece -- (why it is not called a "goose" piece is beyond me). The other two identical triangles are considered to be the "sky" pieces.
Flying geese units are probably the third most commonly used patches in quiltmaking -- following the square and the half square triangle.

The Homespun quilt block is comprised of three common patches -- the flying geese patch, half square triangles and the square.
You might notice that the Homespun block looks familiar. It has similarities to other blocks -- the Cups and Saucers block and the Hands of Friendship block, but on closer inspection you will see the subtle differences.
Other than the quilt layouts illustrated here, you might also look to the other two patterns mentioned above for inspiration for other setting designs of your quilt.
