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 Millstone quilt block was new to me. I quite enjoyed seeing the possibilities with colour. This block is comprised of lots of different elements -- squares, half square triangle pieces, quarter square triangles and flying geese.
For the reason that there are so many bias edges, I have added this quilt block to the intermediate category, although there is really nothing difficult to making the block. By taking care with your piecing and those pesky bias edges, this block will be a very welcome addition to any quilt.
Just as colour plays an important part in the making of the quilt block, it is also the case when choosing the final components to finish off the quilt. This is evident when you look at the sample quilts displayed here.
