alot of classes on machine quilting. I am still so amazed at how little quilters understand the relationship between the needles in their sewing machines and the quality of work that they produce. One of the key ingredients to being successful with machine quilting is using the right needle for the right thread. I have taken a picture of some of the different needles I use depending on the kind of thread I am working with.
On the left are cotton #30 and #40 weight threads. When I use a cotton thread I always use a quilting needle.
In the middle are Superior Polyester Thread and YLI silk. I use Sharp or Microtex needles when I am using either of these threads, and I adjust the size of the needle to the size of the thread. So if the polyester is a #40 I use an 80 0r 90 size needle. With the silk it is a much thinner weight thread #50# or #100 and I use a smaller needle. That only makes common sense. The last thread on the left is my favorite thread, a #30 weight Rayon thread. I sell this on my website , in the notions section. When I use rayon I use an embroidery needle. All of the needles I have mentioned are sharps, they have a very sharp shaft for puncturing through multiple layers. This makes my machine quilting so much better, and I don't have any issues with my threads breaking or fraying because I am using the correct needle with the kind of thread I am quilting with.
I get a great newsletter about thread from Superior Threads and now they have a new blog, I hope you check it out.
