Save money by taping your quilt batting scraps together to make Frankenbatting and save money by Sew Nikki

If you’ve ever looked at your pile of batting scraps and thought “there has to be a way to use this,” you are correct. Frankenbatting is exactly what it sounds like. You piece together leftover quilt batting scraps to make one larger piece instead of buying new batting. It’s practical, it saves money, and it works better than you might expect.

I used this method while finishing my Modern Ohio Star Quilt, which is a scrappy square throw made entirely from stash fabric. I even pieced my quilt backing. So buying brand new batting just didn’t make sense. I grabbed some batting tape from Amazon, pulled out my leftover cotton batting pieces, and gave it a shot.

Here’s exactly how it went and what I’d do again.

What Is Frankenbatting

Frankenbatting is the process of joining smaller pieces of quilt batting together to create one large batting layer. Instead of tossing scraps or letting them pile up, you reuse them.

It’s especially helpful for throw quilts, baby quilts, or anything scrappy where perfection isn’t the goal. If your quilt top is already a mix of fabrics, your batting can be too.

This method works best with cotton batting since it can handle heat from an iron. If you’re using polyester, skip the iron and use a sewing method instead.

Supplies You’ll Need

You don’t need anything fancy to make this work:

Cotton batting scraps
Batting tape (fusible, one-sided)
Iron
Ironing board
Parchment paper (optional but helpful)
Flat surface like a bed or table

If you’re new to batting types, this guide from Amy Smart, Diary of a Quilter breaks down the differences in a simple way.

How to Make Frankenbatting

How to Piece Batting Scraps for Large Quilts (Step-by-Step)

1. Lay Out Your Quilt Backing

Start with your quilt backing. Press it well so there are no wrinkles.

Lay it wrong side up on a bed, table, or even the floor if that’s what you’ve got. The goal is a smooth surface where everything can stay flat.

If you’ve never made a quilt before, check out this Quilt Backing Chart that tells you approximately how much fabric you will need for your size quilt.

2. Layer the Batting Over the Backing

Next, place your batting pieces on top of the backing.

Arrange them until the entire quilt backing is covered. This is where things get a little real. You might have read that batting should not overlap.

I’m going to be honest with you. I had to overlap mine slightly.

When you’re working with scraps, perfectly butting edges together isn’t always realistic. A tiny overlap is better than leaving gaps. Just keep it minimal so you don’t create bulky spots.

3. Join Batting Pieces with Batting Tape

Now take your batting pieces to the ironing board.

Line up two pieces with a slight overlap or edge-to-edge if you can manage it. Then place the fusible batting tape over the seam.

Press with your iron to fuse the tape and hold the pieces together.

If you want to protect your iron from adhesive, lay a piece of parchment paper over the tape before pressing. It’s a simple step that saves cleanup later.

For more on batting fusible products, you can reference Pellon’s Product page for a list of materials.

Repeat this process until all your batting pieces are joined into one large section.

4. Place the Finished Batting Back on the Quilt

Once everything is fused, move your batting back onto the quilt backing.

Smooth it out so it lays flat and covers the entire surface. Check for any thick seams or uneven spots and adjust if needed.

At this point, your quilt sandwich is ready for the quilt top.

Can You Iron Batting

Yes, but only certain types.

Cotton batting can handle heat from an iron, which makes this method possible. Polyester batting cannot be ironed because it can melt or distort.

If you’re working with polyester, you’ll need to join batting pieces using a sewing machine instead of fusible tape.

My Honest Take on Frankenbatting

This worked better than I expected.

The batting tape held everything together without shifting. Once the quilt was layered and quilted, I couldn’t tell where most of the seams were.

It’s not a perfect method, but it doesn’t need to be. For a scrappy quilt made from stash fabric and leftover backing, it fits right in.

I would absolutely use this again, especially for throw quilts.

When Frankenbatting Makes Sense

This method is a great fit if:

You’re making a scrappy quilt
You want to save money on batting
You have leftover cotton batting pieces
You don’t mind a slightly imperfect finish

If you’re working on a show quilt or something very detailed, you might still want to use a single piece of batting.

Yes, you can piece batting scraps together using fusible batting tape or by sewing them. This is a common method called Frankenbatting and works best with cotton batting.

Is it okay to overlap batting

Slight overlap is okay if needed. While edge-to-edge is ideal, a small overlap is better than leaving gaps. Keep it minimal to avoid bulky seams.

Can you iron all types of batting

No, only cotton batting can be safely ironed. Polyester batting should not be exposed to heat and should be joined using a sewing method instead.

Will seams show after quilting

In most cases, seams are not noticeable after quilting, especially in scrappy quilts. Keeping seams flat and minimal helps them blend in.

Is Making Frankenbatting Really Worth It

Frankenbatting is one of those things that feels a little questionable until you try it. Then you realize it’s just practical quilting.

If you’re already using stash fabric for your quilt top and backing, this is the next step in making the most of what you have. It’s simple, budget-friendly, and gets the job done without overthinking it.

If you try it, you’ll probably end up with fewer batting scraps sitting around and more finished quilts. And that’s kind of the goal.
