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.
Free Quilt Block Pattern
The King's Crown quilt block gives you chances to practice your skills on a variety of patches. The centre of this block is made with a square in a square patch. This could be the perfect spot to utilize a "fussy cut" square showing a specific motif, or as is shown here -- a simple plain patch where you can feature an interesting quilting design.
The other patches used are frequently seen in a wide variety of quilt blocks -- the half square triangle, the quarter square triangle, and my favourite patch -- the flying geese unit.
The two sample quilts illustrated both feature lots of free space to showcase your quilting designs. The sky is the limit!
