Inside: How to Make a Perfect Twin Star Quilt Block
The Twin Star Quilt Block is a variation of the Friendship Star block and is ideal for beginning quilters. At its core, it’s only a 9-patch block that uses a split quarter square triangle, which I will demonstrate below.
This is a great block to make because it’s so versatile, and has the added bonus of improving your skills while you learn a new technique.
I tried to do a little research on the Twin Star Quilt block and couldn’t find any historical information, but I know you’re going to love how easy this quilt block is to make. And be sure to grab the FREE PDF instructions below.
How to Make a Perfect Twin Star Quilt Block
This block is very economical. I used some solid fat quarters that were in my stash. As long as you choose fabrics that have a contrast, anything will work.
- Solid Fabric #1 (Orange)
- Solid Fabric #2 (Green)
- Solid Fabric #3 (Turquoise)
- White Fabric (Kona White #1387)
Basic Sewing Supplies Needed
- Sewing Machine
- Its nice to use a 1/4″ sewing foot to help maintain a perfect seam allowance
- Cotton Thread
- I prefer Aurifil 50 wt. thread
- Sewing Pins
- Rotary Cutter with sharp blade
- Acrylic Ruler
- Rotary Cutting Mat
- Iron & Ironing Board
Twin Star – Cutting and Marking
- Qty (2) 5″x 5″ Orange (A)
- Qty (1) 5 1/4″ x 5 1/4″ Green (B)
- Qty (1) 5 1/4″ x 5 1/4″ Turquoise (C)
- Qty (1) 5 1/4″ x 5 1/4″ White (D)
- Qty (5) 4 1/2″ x 4 1/2″ White (E)
Step 1 – Cutting Split Quarter Square Triangles
- Take the white (D), green (B), and turquoise (C) squares and with a pencil make two diagonal lines from corner to corner. Cut along these diagonal lines. This will give you 4 white triangles, 4 green triangles, and 4 turquoise triangles. Note: You only need two green and two turquoise triangles, so set aside the remaining triangles for a second block.
2. Take the two orange squares (A) and with a pencil draw one diagonal line. Cut along this line. You will have 4 orange triangles.
Step 2 – Assembling Triangles
It’s very important to pay attention to the orientation of your green and turquoise triangles. This will matter when assembling your block.
Before stitching, it’s a good idea to layout the triangles as seen in the Step 4 diagram below. I also recommend lowering your stitch length slightly (2mm) and using a walking foot or dual feed.
1. Take one turquoise triangle and one white triangle and stitch together. Repeat.
2. Take one green triangle and one white triangle and stitch together. Repeat with the remaining green triangle and the two turquoise triangles.
3. Trim away dog ears and press seams towards the dark fabric.
Step 3 – Assembling Split Quarter Square Triangles (SQST)
Pay attention to the orientation of your green and turquoise triangles when assembling SQSTs. See the Step 4 diagram below.
1. Take one green/white triangle set and attach to one orange triangle. Press towards orange fabric. Repeat.
2. Take one turquoise/white triangle set and attach to one orange triangle. Press towards orange fabric. Repeat.
You should now have two green/white/orange squares that are 4 1/2″ and two turquoise/white/orange squares that are 4 1/2″. Trim to size if necessary.
Step 4 – Block Assembly
1. Arrange your blocks and SQSTs in correct layout (pictured below).
2. Using a quarter inch seam allowance, sew together across in rows. Press seams in same direction on each row. Alternate pressing direction on each row.
3. Join all rows lengthwise, using a quarter inch seam allowance. Take time to nest your seams.
4. Press your completed block and trim down to 12.5″ square (if necessary).

Don’t you love the Twin Star Quilt Block – especially the simplicity.
Try a different look by using small prints. Make each of the “stars” out of a different fabric from a collection. Or, try using low volume fabric for the background.
Better yet, the options for this simple quilt block are fun to imagine! This is ideally suited for a pillow or you could make several more Twin Star blocks for an entire quilt or piece three or four together for a nice table runner.
The Twin Star Quilt Block is a fun and simple quilt block. I hope you make lots and lots of them.
