I taught a free motion quilting class yesterday and I was explaining the difference between the thread sizes. For some people, thread thickness can be very confusing. It’s hard to compute in our brains why the higher the number, the thinner the thread and the lower the number the thicker the thread. I am going to try to simplify which is which.
Normal sewing thread is usually 50 weight thick.This is the standard in the industry. This is the normal thread you buy at Joann’s or wherever you buy your everyday sewing or quilt piecing thread.
To sandwich my quilts together I like to use a 30 weight quilting thread. (use a 90-14 needle or higher) It’s a little thicker and shows up nicely whether you are machine quilting or hand quilting. There are many good brands of thread but my personal preference is Sulky quilting thread solid or variegated, or King Tut solid or variegated. King Tut has nice large spools. Great if you are quilting a large quilt that will use a lot of thread.
There is one more thread for quilting. It’s a 12 weight that is much thicker and nice for hand quilting. It gives a nice texture to the finished quilt. If you use in a machine I would use a top stitch needle like a 90-14 or 100-16
Embroidery thread is 40 weight. This is the standard for anyone using embroidery thread for their machine embroidery designs. This thread is a little thicker than your normal sewing thread to give you more depth in your design. It can also be used for quilting your quilt sandwich when used on a machine. It has more sheen and can look very nice on the more modern style of quilts. For quilting you would want to use the same weight thread in needle and bobbin.
60 weight thread is what you use in the bobbin of your machine when doing machine embroidery. It comes in several colors ie; white, tan, cream, grey and black. You can buy it in pre-wound packets or your can buy Finishing Touch bobbin thread in spools that you can wind on your own machine if that’s what you prefer. Also, some machines don’t like pre-wound bobbins. My Brother Quattro and Dream machines love both pre-wounds as well as bobbins I wind myself. There is also a 60 weight cotton thread you can buy to use in your bobbin if you want the back and front of your project to look the same such as in lettering. 60 weight cotton thread is also nice to use when sewing applique’s on the machine or by hand.
The last one I want to talk about is a beautiful thread you can use for heirloom sewing and for tacking down appliques. It’s 100 weight thread. It’s the finest thread on the market. It can be purchased in cotton and silk. Very delicate and lovely when sewn.
I hope this helps any one who may have been confused about thread weight and the use of each type of thread. Except for embroidery I always use the same weight thread in my needle and bobbin. My favorite threads for sewing and piecing are Aurifill, Mettler, Superior, Sulky and Gutterman. For embroidery threads I like Floriani, Isacord, Brother Madeira, Robinson Antone and Sulky. All are excellent brands.
