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 Dancing Shoofly quilt block is new to me, and I always love to discover new blocks to play with.
This is one of those "block in a block" type of instances, because the centre of the quilt block is a separate block all on its own. Not to worry though, as it is all quite easy to construct this nine patch block, as it uses only squares, rectangles and flying geese patches.
I played around quite a bit with the sample quilts illustrated and had fun doing so. You will find the same thing when it is time for you to decide on your design layout. Enjoy!
