This is probably the most basic star block. But it is a classic favorite that looks good in any fabric, and is easy to re-size to make smaller or larger.
My blocks finish at 11" (10.5" after squaring…if you square them).
Start with 8 – 4" background squares, 1 – 4" center square, and 8 – 3" squares for the star points.
On 4 of the background squares place a 3" square in a corner right sides together and sew from corner to corner. The tape trick comes in handy again on these blocks. Cut the corner off leaving 1/4" and press open.
Place another 3" square in an adjacent corner and repeat the steps.
Layout your squares again and sew the squares into three rows.
Press the seams of each row in opposite directions, and sew the rows together.
The finished block should be 11". I squared my blocks up to 10.5".
48 blocks (6 in each row, 8 rows) makes a perfect twin size at 60" x 80".
