This block merges a quarter square triangle with a half square triangle to create what I'm calling a half quarter square triangle. ( I don't know if that's the right name, but it made sense to me! )
Making half quarter square triangles (HQSTs) using a traditional method with two half-square triangles (HSTs) results in blocks in alternating directions -
This alternate method uses strip piecing to create HQSTs which all orient the same way.
Start with strips equal to the size of the finished block, not including seam allowances. You can use any number of strips - odd or even - and any length. You will need approximately 2 1/2 times more of the background (HST) fabric than the accent (QST) fabric.
Sew alternating background and accent strips together along the long edges. Press seams open throughout.
Note: Starting with strips cut on the cross-grain will result in finished squares on the bias. Start with bias-cut strips to finish with cross-grain squares.
Cut perpindicularly into strips equal to the original strip width.
Sew these together with additional strips of the background color, keeping the alternating strips oriented the same direction.
Starting in the upper corner, cut at a 45 degree angle through the center of the accent fabric.
Continuing cutting in this manner until all accent squares have been divided.
Cut these strips again in the opposite direction through the backgound fabric to create a series of HQSTs.
The resulting half quarter square triangles are all identical!
