How to Join Quilt Batting Pieces – Use your Leftovers!

If you’re wondering how to join leftover quilt batting – sometimes affectionately known as “frankenbatting” – then I’ve got you covered with this very quick and easy to follow tutorial.

Materials Needed to Join Leftover Quilt Batting

– Batting scraps – Sewing machine and presser foot – Thread – Long Quilting ruler – Rotary cutter – Cutting mat


First things first, figure out which pieces you need to join together to be large enough for your quilt top. Smaller pieces may want to be saved for small projects, but those larger pieces of are just waiting for you to join them together and put them to good use. And this doesn’t have to be just for your next quilt; there’s a lot of different ways to use batting.

Pull out your leftover batting pieces


To start – spread out two pieces of quilt batting on your cutting mat and slightly overlap the batting edges – roughly overlap ½ inch to 1 inch.

Place your batting so it overlaps


Using your quilting ruler and rotary cutter (or other cutting tool), place the ruler on the edges of the batting (middle of the overlap).

Get straight edges to join by cutting both pieces at once


Set your sewing machine to a wide zig-zag stitch.

Time to Sew

Take your time so you don’t end up with little gaps where the zig-zag stitch didn’t catch – your finished quilt project will thank you!
