POLYESTER

The best quilt batting for machine quilting is generally considered to be a low-loft, polyester batting. This is because polyester batting is less likely to shift or bunch while being quilted by a machine, and it also holds up well to repeated washing and use. Additionally, polyester batting provides a smooth and stable surface for machine quilting, which can help to prevent skipped stitches or other quilting issues. Other types of batting, such as cotton or bamboo, may also work well for machine quilting, but polyester is generally considered to be the best choice due to its ability to withstand the high-speed and repetitive motion of a sewing machine.

Would a double layer of cotton and wool be a good combination for machine quilting?

A double layer of cotton and wool batting could be a good combination for machine quilting, as both cotton and wool have unique properties that can complement each other. Cotton batting is breathable and provides a nice drape, while wool batting is naturally insulating and can add extra warmth to a quilt.

However, it’s important to note that using a double layer of batting can add extra thickness and weight to the quilt, which may be more difficult for some machines to handle, and it can also make the quilt heavier and bulkier. Additionally, both cotton and wool batting have a tendency to shrink, so it’s important to pre-wash and dry them before use, to prevent any shrinkage after the quilt is finished.

If you’re set on using a double layer of cotton and wool batting, it’s recommended to test the quilting on a small swatch or piece of your quilt first to ensure that your machine can handle the thickness and weight, and to make sure that the quilting looks as desired.
