Sometimes it is difficult to find a quilt pattern that can be accomplished successfully by a group of quilters because each individual's piecing skills and measurements can be their own. A group of blocks made by different individuals can be challenging to put together into a nice flat quilt top.
The secret to the success of this quilt block is the "floating" star. The white pieces around the star are deliberately pieced larger than required. After the star block is finished it is squared to 9 1/2". This squaring after piecing ensures that all blocks are exactly the same size. The sashing rectangles that surround the stars finish at 2 3/4" wide and are either 7 1/4" long for the top of the block or 9" long for the sides of the block. Because these blocks are all pieced from scraps in each quilter's existing stash, the only cost outlay for the group is the batting, backing and long arm quilting.
UPDATE: This pattern is an Atkinson Designs quilt called "Lucky Stars".
