The Double Star Quilt Block
The Double Star quilt block is a Sawtooth Quilt Block with an extra round.
You can see the Sawtooth Star in the center of the block. When you add the additional round, the block gets a lot bigger.
The additional round is again made with Flying Geese patches and squares in the corners. As you can see from the above picture. the outer Flying Geese Unit covers the entire width of the inner Sawtooth Star.
The Flying Geese Unit is always exactly twice as long as it is wide. Be sure to make your first Sawtooth Star taking that measurement into consideration. If you first star finishes at 6 inches, then the outer Flying Geese units will finish at 6x3 inches. The block would then finish at 9 inches.
That is an easy size to place next to a 9-patch block with 3 inch grids, but as you can see from the picture at the left, this is a basically a 4-patch block.
It the inner star finished at 4 or 8 inches, you would end up with a 6 or 12 inch block, which would work better with other 4-patch blocks.
Keep that in mind when deciding what size to make your beginning star.
