The Crystal Star quilt block is yet another variation on the Sawtooth Star—this time a square in a square is added to the center for interest.
This block is also commonly referred to as a:
We'll use the connector corners technique for the center and Flying Geese. Add four more cut squares and that's all there is to it. No special tools. No special rulers. All you need are your basic quilting supplies.
All will be crystal clear as you follow along in the tutorial. Let's get started!
Sample Block Size: 8"(8-1/2" unfinished)
Grid size: 2"
All seams are 1/4".
When you are instructed to press, first press the pieced unit flat to set the seam. Suggestions are provided throughout these instructions on which way to press the seam allowances.

A directional white and black print is used for the background.
Instructions are provided on how to cut and mark the patches so that the design moves across the block in one direction.
As you piece, flip back the corner of the patch BEFORE stitching to ensure that it is in the correct position. This quick check is much faster than having to rip out a patch that should have been turned a quarter turn.
While we've used the connector corners method here in this tutorial, the 'four at a time' Flying Geese method would also be an efficient way to make the Geese units, too.
This block is the perfect example of why you want to make a practice block.
Though there seemed to be plenty of contrast between the fabrics laid out next to each other, the piecing looks a bit 'mushy' in the finished block.
To remedy this, I'd choose a more 'white' black and white print for the background next time.

The patches for this block are below. Notice particularly how the rectangle patches are cut—two in each direction of the print. This is to keep the print design flowing from top to bottom of the block.
Flying Geese Units
Mark a diagonal line from corner to corner on the back of the eight #2 squares for the star points.
Align one of these marked squares with the end of a rectangle patch. The drawn line bisects one of the corners.
Stitch on the line. You can chain stitch these pieces.
Press flat. Trim the seam allowance on the side of the stitching line closest to the corner.
Press the square open and towards the corner.
Align another #2 with the open end of the rectangle. The drawn line bisects the corner on the same long edge as the previous square did.
Stitch on the drawn line.
Press flat, trim the seam allowance and press as you did for the first square.
If any of the #2 squares extend past the #1 rectangles, trim the patches even.
For this sample 8" finished block the Flying Geese measure 2-1/2" x 4-1/2" at this point.
Square in a Square Center
We'll use the connector corner technique again.
Mark the backs of only four of the eight #4 patches with a diagonal line from corner to corner.
For a directional print, you'll want to mark the lines as shown below. For two the print runs top to bottom. For the other two, the print runs left to right.
With RST, align the edges of two of the #4s with the larger #3. The ends of the drawn lines touch the sides of the large square.
Stitch on the line. Press flat, trim the seam allowance on the side of the stitching closest to the corner.
Press the patches open and toward the corners.
Repeat for the two remaining marked #4s.
If the #4 patches extend past the edges of the large squares, trim them even.
Your finished square in a square should measure 4-1/2" x 4-1/2" for this 8" finished block.
Lay out the finished units and remaining cut squares for this Crystal Star block.
Sew them into rows. Press the seam allowances away from the Flying Geese.
Stitch the rows together, pinning if needed to help match the seams.
This is what the Crystal Star quilt block looks like from the back side.

It's so easy and works so well you'll wonder why you didn't think of it yourself!
