Leah Day the Free Motion Quilting Teacher -Guru -- only uses Isacord Threads for her Quilts and her many online Classes
Isacord polyester embroidery thread a high quality, strong, yet very
thin thread designed for embroidery, but also perfectly suited for
applique and free motion quilting
Isacord - this 40 wt. thread is very thin, making it an excellent
choice for free motion quilting designs that require a lot of travel
stitching. Isacord is also very strong and able to take the high speed and intensity of machine quilting and embroidery
Isacord is also virtually lint-free.
Cheaper threads throw off balls of lint that can clog up both the bobbin and top area of a machine. This lint can easily destroy a good machine so make sure to brush out your machine top and bobbin area often.
For best results, always match the color and brand of thread in both the top and bobbin of your machine.
Mismatching thread brands, or using cheaper thread in the bobbin, is the
#1 reason why quilters struggle with tension issues and poor stitch
quality when free motion quilting.
The thread you use DOES matter for the overall outcome of your quilt. For best results, also useLittle Genie Magic Bobbin Washersinside your bobbin case to reduce the number of thread nests and breaks while you quilt.
