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.

Black Hole

Free Quilt Block Pattern

The Black Hole is an easy block for construction, as it has only one quilt patch to learn -- the flying geese patch.

This quilt block is also part of the category uneven nine patch as it is constructed just the same as a nine patch, but all of the units are not the same size.

This time, I have shown four different quilt layouts in the samples illustrated, just so you know that a simple block does not mean that your quilt will be boring. Enjoy!
