Select your batting scraps - enough to make a batting sheet that's large enough for your latest project. Ensure your batting scraps are all the same loft/quality.
|Starting to join the scraps together|
Switch your machine's foot to one suitable for a wider stitch and set your machine stitch to double overlock (stitch no 8 on the Bernina 440QE). I'm using stitch length 2.1 and stitch width 5.5 but you can adjust this to suit your needs. You can also use a zigzag stitch if you prefer. If you can set your machine stop to needle down - this will give you more control of the fabric should you stop sewing.
Butt the edges of the scrap pieces up to each other and sew them together using the overlock stitch. There's no need to pin the batting scraps - just adjust your sewing speed to one that's manageable for you to bring the two pieces together by hand as you sew. Add additional sections of batting scraps to achieve the required sheet size.
When you're sewing the scraps together it's okay if they overlap in places, it won't make too much thickness when the sheet is finished, in fact, it is better to overlap than to leave a gap.

This technique is really great and, depending on the weight of the top and bottom sheet fabrics, the seams won't be visible through the finished quilt. Of course, if you're making a really special quilt as a memory, a gift or to sell then you wouldn't want to use pieced batting but for an everyday quilt, it works really well and saves you money.
