Split Quarter Square Triangles

The quarter square triangle is another basic building block for quilters.  There are many layouts for this block, and it is used to make other beautiful quilting blocks.

This block is usually made in pairs. It is made similar to the half square triangle quilt blockand the quarter square triangle quilt block.

the first step making the split square triangle quilt block The first step when making the split quarter square triangle block is the same as the first step for the quarter square triangle block. Follow the instructions on the quarter square triangle page.  Remember  that you cut the 2 squares 1 1/4 inch larger than the desired size of the finished block for this first step.

After you have the 2 half square triangle blocks, you are ready for step 2.  Cut a single square of fabric. Cut it the same size as the  half square triangle block you just made. It will be 3/8 of an inch smaller than the first large square in step one.

the second step making the split quarter square triangle quilt block Place this square right sides together with the half square triangle block.  Draw a diagonal line from one corner to the opposite corner.  Notice that the line is drawn over both the light and dark fabric.  Sew 1/4 inch on both sides of the line, and then cut down the middle.

the finished split quarter square triangle quilt blockOpen up your two blocks, and press.  You will have two quarter square triangle quilt blocks.

Note:  The 2 split square triangle blocks cut from the same square will always be mirror images of each other.
