Crystal Star Quilt Block Pattern

From our Free Quilt Block Patterns Library


Crystal Star quilt block

Skill Level: Beginner

Grid: 4x4

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 three fabric block is also commonly referred to as a:

Joining Star
Lone Star
Peaceful Hours
Star of Virginia
Texas Star

We'll use the connector corners technique for the Square in a Square 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.

Let's get started!




Construction Instructions


Crystal Star quilt block design

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 fabric. 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 with this type of fabric, 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 be a good choice to make the Geese units, too.


Step 1: Cut the fabric patches

Fabric A:
(white and black)

Fabric B:
(Red)

Fabric C:
(Orange)

Eight 2-1/2" squares
Four 2-1/2" x 4-1/2" rectangles

Eight 2-1/2" squares
    

One 4-1/2" square

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 fabric print flowing from top to bottom of the block.

Step 2: Assemble the units

Flying Geese Units

Mark a diagonal line from corner to corner on the back of the eight Fabric B/red 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.


Stitch one connector corner to each background rectangle

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 Fabric B square 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.


Stitch the second connector corner

Press flat, trim the seam allowance and press as you did for the first square.

If any of the Fabric B/red squares extend past the Fabric A/white and black rectangles, trim the patches even.

Your 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 four of the eight Fabric A/white and black squares 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.


Mark the connector corners for the center square

With RST, align the edges of two of the Fabric A/white and black squares with the large Fabric C/orange square. 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.


Stitch the first pair of connector corners
After the seam allowances are trimmed.

Press the patch open and toward the corner.

Repeat for the two remaining corners.


Add the final connector corner to the center square
The red arrow points to my anchor cloth

If the Fabric A/white and black 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".


Step 3: Assemble the block

Lay out the finished units and remaining cut squares for this Crystal Star quilt block.


Lay out your finished units

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. To press a perfectly flat block—even with the added layer of fabric from the connector corners—use the Best Pressing Technique for Quilt Blocks. It's so easy and works so well you'll wonder why you didn't think of it yourself!
