How to Cut Fabric for a String Quilt Block

Preparing Your Fabric Strips
Start by cutting your fabric into 2.5-inch strips. This size works perfectly because it matches standard jelly roll strips.
You can:
- Use scraps of any size
- Cut from yardage
- Mix colors for a scrappy look
A quilting ruler like a Stripology ruler can speed up the process by allowing you to cut multiple strips quickly and accurately.
Pro Tip for Better Results
Always square up your fabric before cutting. Straight edges ensure your this Quilt Block comes together neatly.
Preparing the Foundation for Your String Quilt Block

Why Use Foundation Paper
A String Quilt Block is much easier to assemble using foundation paper. It stabilizes your fabric and keeps everything aligned.
Cutting Your Foundation Pieces
- Final block size: 10 inches
- Foundation size: 11 inches
This extra inch gives you room to trim and square up later.
You can use:
- Tracing paper (best option)
- Regular printer paper (avoid thick paper)
The lighter the paper, the easier it will be to remove after sewing your Quilt Block.
Step-by-Step: How to Sew a String Quilt Block

Step 1: Place Your Guide Strip
Choose a bold fabric (like orange) as your guide strip.
- Place it diagonally in the corner of your foundation paper
- This strip sets the direction of your entire Quilt Block
โ ๏ธ This step is critical. If your guide strip is off, your final design will be affected.
Step 2: Add Your First Fabric Strip
- Place your next strip right sides together with the guide strip
- Sew along the edge using a quarter-inch seam
Once sewn:
- Flip the fabric open
- Press it flat
Step 3: Build Your String Quilt Block
Continue adding strips:
- Alternate sides of the guide strip
- Place each strip right sides together
- Sew โ Flip โ Press
Repeat this process until your entire foundation paper is covered.
This method makes building the Quilt Block quick and efficient.
Step 4: Trim Excess Fabric
If fabric extends beyond the paper:
- Trim it off
- Keep edges manageable
Donโt worry about perfection here your Quilt Block will be squared later.

Step 5: Trim to Size
Flip your block over so you can see the foundation paper.

This step gives your Quilt Block its signature look.
Removing the Foundation Paper
Once trimmed:

As a Baby Lock Educator, I always recommend taking your time when removing foundation paper to avoid putting stress on your seams.

Pressing after each seam keeps your String Quilt Block flat and accurate.

Tips for a Perfect String Quilt Block
Tips from a Baby Lock Educator
Use Contrast for Impact
A bold guide strip makes your String Quilt Block design pop. Choosing a strong, standout color helps define the direction of your block and makes the overall quilting design more visually striking.
Keep It Scrappy
Mix colors and prints for a dynamic quilt. One of the joys of creating a String Quilt Block is embracing a scrappy look, which adds personality and charm to your quilting project.
Stay Consistent
Keep strip widths similar for a cleaner finish. While quilting allows for creativity, consistency in strip size will help your String Quilt Block look more polished and professional.
Work in Batches
Cut and sew multiple blocks at once to save time. Batch working is a great habit in quilting, helping you stay efficient and maintain momentum throughout your project.
