provide an awesome amount of color waves for a reasonable cost. Mine came with 42
fabric swatches. If you don’t want to do it that way you would need 9 different fat
quarters or 5 different fabrics at ½ yard each.

Cutting Your Fabric


The first step in this bubble quilt tutorial is cutting your fabric correctly.
You will be working with two different fabric sizes:
- The top section uses 5-inch squares
- The bottom section uses 4.5-inch squares
This size difference helps create structure and dimension in the final quilt.
Why Measurements Matter
Precision is important. The 5-inch top squares allow enough fabric for pleating, while the 4.5-inch bottom squares act as a guide to keep your folds consistent and even. You can scale this bubble quilt up or down, but avoid going too small because the pleating becomes difficult to manage.
Step by Step Pleating Method






Pleating is the most important technique in this tutorial. This is what gives the quilt its signature “bubble” effect.
Take one 5-inch square and begin the pleating process:
1. Fold the fabric slightly into the center
2. Create a small pinch or pleat
3. Use your 4.5-inch square as a guide for alignment
4. Make sure the pleat does not exceed the bottom square width
Repeat this process on all four sides.
Perfect Pleating
Throughout tutorial, consistency is key. Always check your alignment against the bottom square before clipping.
Use wonder clips to hold each pleat in place as you work your way around the square.
Secure Each "Bubble"


After pleating, the next step in this tutorial is securing each section.
Once all three sides are pleated, LEAVE THE BOTTOM OPEN:
• Clip each fold securely with wonder clips
• Check alignment carefully
• Ensure all pleats are evenly spaced
Repeat this process for every fabric square in your quilt.
Machine Setup


For this tutorial, set up your sewing machine with:
• Regular J foot
• Piecing Stitch Setting start with the (right stitch) then move your needle to the right three times with the width right button.
• needle (90/14)
Stitching the Pleated Squares


Sew slightly less than a quarter inch from the edge (Scant quarter), following the crease lines carefully. Piecing Stitch Setting start with the (right stitch) then move your needle to the right three times with the width right button.
In this tutorial, you should:
• Sew along the pleated edges along the three sides
• IMPORTANT Leave the bottom section open for stuffing
• Maintain consistent seam allowance
• Make sure to reverse stitch at the start and finish
Repeat for each square until they are all complete
Assemble Columns and Rows


Once individual squares are sewn, you will begin assembling rows.
Connecting Rows Together
In this tutorial, rows are joined using a quarter-inch seam. Use Piecing Stitch Settings with the (Center stitch) no need to adjust the needle now.
• Place right sides together
• Align seams carefully
• Stitch across the top and bottom sections
• Leave bottom openings accessible for stuffing
Continue building rows until your quilt reaches your desired size.
There will be 10 columns across and 12 rows down.
Stuff Your Bubble Quilt


This is where your quilt starts to take shape.
Add Polyfill
You will use polyfill to create the “bubble” effect.
- Open each section carefully
- Add small amounts of stuffing
- Avoid overfilling (important for sewing later)
Be Careful: Don't Overstuff!
Overstuffing this bubble quilt can make it difficult to sew the final seams. The quilt should feel soft and puffy, not overly firm.
Close and Secure the Bubble Sections


Stitching Sections Closed
Before attaching your next row, you need to close the stuffed sections.
This step ensures stability:
- Fold pleats back into place along the bottom, clip with wonder clips
Sew across openings securely, using a scant quarter as before. Piecing Stitch Setting start with the (right stitch) and move the needle to the right three times which will allow you to create a scant quarter
Ensure stuffing stays inside each bubble
This makes attaching additional rows much easier and cleaner, avoid overstuffing
Adding Additional Rows


Now you will build the full quilt structure.
· Attach filled rows to empty rows using the Piecing Stitch Setting with the (Center stitch) no need to adjust the needle now
- Always align seams carefully, I used pins to line up all my seams together before sewing into place
Repeat this process until you finish the quilt.
Finishing Quilt Edges


Cleaning Up Threads
Trim any loose threads and tidy edges.
Adding Batting
Batting is optional but recommended:
- Cut batting slightly smaller than quilt top 43” x 45”
- Cut Backing Fabric 50” x 41” The backing also serves as your binding.
Create a Quilt Sandwich


• Place the backing Fabric pretty side down
• Use 505 Fabric Adhesive spray, and stick to the back of the bubble quilt, this keeps everything in place
• Place the Bubble Quilt top onto the wrong side of the quilt backing
• Make sure nothing has shifted
• Pin all three layers into place
Tack Down Stitching


• Put your sewing machine on a button hole setting
• Place a thread that matches your fabric so it will not be noticable
• Drop the feed dogs
• Tack in the center with a thread that will not be noticed on the reverse of your quilt. This does not need to be done on every one. Just enough to stop the backing and front from moving.
Create Binding


Binding gives your quilt a polished, professional finish.
Folding Technique
Use a double or triple fold method:
- Fold backing fabric over in half
- Fold again to create clean binding edge. Binding is personal, I prefer it to be narrower so I folded over three times
- Clip into place with wonder clips
Corners
For corners:
- Cut excess bulk
- Fold neatly into a diagonal
- Continue binding around quilt edges
Sew Final Edges
· I prefer to hand sew all my bindings, I find you can control the bulk so much better. You can sew by machine if you like!
