What Type of Needle Do I Have on the Sewing Machine?

Thursday I am teaching a Threads and Needles class at my favorite Bernina store, Sew Complete.  I have a doctorate in Threadology, don't you know.  You can read about it way back on my first few posts in the fall of 2010.  Actually, anyone who pays the class fees and spends a few days at the School of Threadology at Superior Threads in Utah will get the diploma, so the "degree" should not impress you too much!  I used to teach a  Threads and Needles class at Sew Complete a lifetime ago, or so it seems.  I think it really was only 15 years ago, but it seems longer than that.  The most amazing thing, however, is that I still have my notes from that class, the "bad needle and bad thread" examples, and the little magnifying glasses I hand out to students so that they can see, up close and personal, the bad needle tips.  Where I lived when I taught the classes was three houses ago.  Think about it.  Three moves.  You may not be surprised that I have the class info, but I was pretty pleased.  I also used to teach a class called "Beyond the Basics" on a Bernina 1630, the top of the line back in the 90's.  One of the projects was a Needle Keeper.  You programmed your machine to stitch out the names of the different types of needles, and the most popular sizes of those needles.  You can store slightly used needles in the right spot, or mark what type of needle you currently have in the machine.  So, blog readers....what type of needle do I have in my machine right now?  Yep, a 90 Topstitch.  The above Needle Keeper is one that I designed just today in my Bernina V6 software.  The original one that I taught in the "Beyond the Basics" class is missing.  I can't find it.  I have moved three times, after all.  What do you expect?  Jerilynn
