Have you ever wondered how to make stained glass quilts that look amazing? Today, I’ll show you an easy way to create a beautiful stained glass quilt using the second slash technique. This method turns simple fabric squares into stunning quilt blocks with a magical window-like effect. Let’s get started on this fun project that even new quilters can master!
What You’ll Need for Your Stained Glass Quilt
Before we start cutting and sewing, let’s gather everything you need:
| Materials | Details |
|---|---|
| Fabric squares | Four 10-inch squares (you can use layer cake pieces) |
| Clover bias tape | Black for dramatic fabrics, white or silver for subtle fabrics |
| Sewing machine | With regular or twin needle option |
| Rotary cutter & mat | Rotating mat is helpful but not required |
| Iron | For pressing seams and applying bias tape |
| Ruler | For measuring and trimming blocks |
The great thing about this project is that four fabric squares will actually make four complete quilt blocks. This makes it perfect for using up fabric you already have or for trying out new color combinations.
Understanding the Second Slash Technique
The second slash technique is a simple cutting method that creates interesting diagonal pieces. Instead of complicated patterns, you’ll make just two cuts through stacked fabric squares. When rearranged, these pieces create a beautiful design perfect for the stained glass effect.
What makes this technique special is how the bias tape outlines each seam, just like the lead lines in real stained glass windows. The contrast between your colorful fabrics and the dark bias tape creates that magical stained glass look.
Step-by-Step Instructions
Preparing Your Fabric
Start by choosing four squares of fabric with colors that look good together. I like using 10-inch squares, but you can use any size. Just remember that the final size of your blocks will change based on your starting squares.
Be sure to keep the pleats evenly spaced to achieve a polished look. This is important because we’ll be cutting through all layers at once.
Making the Second Slash Cut
Place your stacked squares on your cutting mat. Instead of cutting straight across, make a slight angle cut through all four layers. Don’t make the angle too extreme – a gentle angle works best.
Turn your mat around and make a second cut, also at a slight angle. You now have four sections from each original square, giving you a total of 16 pieces.
Arranging Your Blocks
Separate your cut pieces into four sets. Each set will make one complete block. Starting in the top right corner, lay out your first set in this order: top right, top left, bottom left, bottom right.
For your second set, start with the same fabric in the top left position. Continue this pattern for all four sets. This creates a nice mix of fabrics without having to label or number your pieces.
Sewing the Blocks Together
Take the top two pieces of each block and sew them together with a quarter-inch seam. Do the same with the bottom two pieces. Press these seams open, not to the side as you might usually do in quilting. This reduces bulk when we add the bias tape later.
Next, sew the top half to the bottom half of each block, matching the center seams carefully. After sewing, you’ll have four complete blocks.
Adding the Bias Tape
Cut pieces of bias tape slightly longer than your seams. Remove the paper backing to reveal the adhesive. Place the tape directly over each seam and press with an iron to secure it in place.
Sew along both edges of the bias tape to secure it. If you have a twin needle (4mm size 80 works well), you can sew both sides at once. Otherwise, sew down one side and then the other.
Trimming Your Blocks
Place your ruler on the block with the 45-degree angle line running from corner to corner. Line up the 9-inch marks (or your desired final size) along two sides. Make sure you have excess fabric on all sides to trim.
Cut along the ruler edges to create perfect square blocks. Repeat for all blocks.
Assembling Your Quilt
Arrange your blocks in a pattern you like. Sew blocks together in rows with a quarter-inch seam, then join the rows together.
For the stained glass window effect, add bias tape along all the seams between rows. Start with horizontal rows, then add vertical strips from top to bottom.
Adding Borders
Finish your quilt with borders. Add a first border (about 2 inches wide) all around the quilt. Then add bias tape along the top, bottom, and sides of the quilt. This creates nice squared-off corners. Add a final wider border (about 4 inches) for a finished look.
Tips for Success with Stained Glass Quilts

Keep your cutting angles gentle – dramatic angles make it harder to piece accurately.
Press seams open to reduce bulk under the bias tape.
When trimming blocks, take your time to ensure they’re all exactly the same size.
Choose bias tape color carefully – black creates the most dramatic stained glass effect, but lighter colors work well with subtle fabrics.
If you make a mistake, don’t worry! The bias tape covers small imperfections in your seams.
Frequently Asked Questions About Quilting
What are the three essential quilts that every woman should create?
Traditionally, quilters speak of three important quilts in a woman’s life. First is the freedom quilt, made as a young person learning to quilt. Second is the marriage quilt, created for her wedding day. Third is the masterpiece quilt, representing her finest work and often passed down as an heirloom.
What is the most famous quilt pattern?
The Log Cabin pattern is widely recognized as the most famous quilt pattern. It features a central square surrounded by strips of fabric arranged in a spiral pattern. This design dates back to the 1800s and remains popular today. Many quilters start their journey with this classic pattern.
What is the easiest quilt pattern?
The Nine Patch quilt pattern is perfect for beginners. It uses simple squares arranged in a 3×3 grid. You only need straight cuts and straight seams. This pattern teaches basic quilting skills without complicated pieces or matching points.
What are the basic steps in making a quilt?
Making a quilt involves five main steps. First, choose and cut your fabric pieces. Second, sew these pieces together to create your quilt top. Third, layer your top with batting and backing fabric. Fourth, quilt these layers together. Finally, bind the edges to finish your quilt.
What is the cheat quilt?
A cheat quilt, also called a shortcut quilt, uses pre-cut fabrics or panels to speed up the quilting process. Many quilters use jelly rolls (pre-cut strips) or charm packs (pre-cut squares). These shortcuts help create beautiful quilts in less time. While some traditionalists prefer cutting their own pieces, there’s no shame in using these time-saving options.
