The Double Star quilt block pattern is made from a hybrid of a half and quarter square triangles, and rectangles and a square. It uses four fabrics.
Skill Level: Confident beginner
AKA: Hope of Hartford
In order to piece the unit we'll use a technique known as 'partial seams' or 'puzzle piecing'. No special tools, rulers or templates are required. The patches are all rotary cut.
It's a fun little block to make that looks more complicated than it is. A couple of pins makes everything easy.
Block Size: 7-1/2" finished (8" unfinished) for this tutorial
Grid Size: 1-1/2"
All seam allowances are 1/4".
When you are instructed to press, first press the pieced unit flat to set the seam. Then open the patch, pressing from the front. The direction to press the seam is included at each step in this tutorial.
For QST units, I like to start with over-sized patches and trim to actual size after stitching. The over-sized units that I cut and used for this lesson are in parentheses ().

In the photo below I have not yet sub-cut the Large Star Points (yellow print) squares.
Stitch the QST units
The quarter square triangle units in this block are pieced from individually cut patches. The units are identical. There is no mirror imaging.
With RST, align the edges of one background triangle to one Small Star Point triangle. Double check the position of the patches to insure they are in the right position. Stitch.
Repeat for the three remaining pairs. To prevent sewing errors, keep the patches in the same order—the blue background fabric is always on top in the photo.
Press seam allowances toward the darker patch (blue).
You're ready for the next seam.
Align the long edge of this pieced blue and orange unit with the long edge of the Large Star Point triangle. Stitch.
Press seam allowances toward the larger triangle to reduce bulk.
If you need a refresher on trimming quarter square triangle units to size, click here to review this technique in Quarter Square Triangle, Technique #1, Steps 6-7. The center measurement for our Double star quilt block is 1-3/4".
Repeat for the remaining 3 quarter square triangle units.
Add the background rectangle
With RST, align the long edge of a background rectangle with the Small Star Point side of the QST unit. Pin if needed. Stitch.
Press. Seam allowance toward the background fabric. Repeat for the 3 remaining units.
To construct this block the first seam is a partial seam. This is done to create an edge equal in length to the remaining units.
With RST, align the center square with the corner of the Large Star Point fabric. Pin if needed. You will stitch along the long side of the QST unit for a little more than half the length of the center square. Our stitching is between the black lines.
Press with seam allowance towards the center square.
With RST, align the next QST unit with the edge of the Center/QST unit. Stitch.
Press. Seam allowance towards the QST-unit.
Repeat for the third unit, pressing towards the center square.
Add the fourth. Pins were helpful to keep the layers evenly together during sewing. Press the sewn seam allowance away from the center.
This is how the block looks from the front before pinning the last, partial seam.
For the last seam things get a bit lumpy. Nothing that a few pins can't tame.
In the photo below, you can see how I've pinned to align and hold the edges. The far right pin is inserted past the original stitching line. This is to help hold things flat and out of the way.
Stitch this seam.
Press, seam allowance towards the center square.
This is how the block looks from the back.
Your finished Double Star Quilt Block from the front.
You may wish to cut the squares for the quarter and half square triangles slightly larger and then trim them to size after stitching. In the tutorial I cut these squares 1/4" larger.
