Both of the blocks illustrated on this page contain quarter square triangle units:
- Quarter-square triangle units form the points of the star in the Ohio Star quilt block, top.
- The traditional Card Trick quilt block, shown beneath the star, is made from a combination of half-square triangle units and quarter-square triangle units in different configurations.
Quick Pieced Quarter Square Triangle UnitsWe've used half-square triangle units to make many of the quilt blocks found in patterns on About Quilting. We'll put half-square triangle units to work again here, using them as parents for our quarter-square triangle patchwork units.
