Half-square triangle units are simple to quick-piece with 5-7/8" squares, and the sandwich method is a good technique to use when you're sewing a scrappy quilt. Each pair of black/batik squares produces two identical half-square triangle units. Cut one black 5-7/8" square and one batik square of the same size to make two identical half-square triangle units, or two black squares and two different batiks to mix it up (you can use the extra units in additional blocks).
- Sew a 3" x 3" batik square to one side of a black square of the same size. Press seam allowance towards the black square. Repeat to make three more batik/black combination units.
- Sew two Step 1 units together, placing blacks on the diagonal from each other and butting seam allowances for a perfect match. Press new seam allowance either direction. Repeat to make a second four-patch unit.
- Use the easy sandwich method to make two half-square triangle units from a 5-7/8" black square and a batik square of the same size. When complete, the two units produced should measure 5-1/2" x 5-1/2". (Repeat if you have opted to make a scrappier block with another unit combo.)
- Arrange the units into two rows as illustrated. Sew components of each row together.
- Press center seam allowances in opposite directions and then join the rows. Press. The quilt block should measure 10-1/2" x 10-1/2".
