Variable Star Quilt Block Calculator
This is a basic nine-patch layout. To calculate the fabric cuts, divide the finished block dimensions by 3, as you’ll have 3 rows of 3 – or nine – block units. This gives you finished units of 3″ to make a 9″ finished quilt block. Add your 1/4″ seam allowance around all edges to make the 3-1/2″ center and corner square units that will finish at 3″ when the 9-patch Variable Star blocks are sewn into your quilt. To make the quarter square triangles you add 1-1/4″ to the finished unit size, or cut at 4-1/4″ for the 9″ finished block. Here are the cut sizes needed for popular finished quilt block sizes.
