I use any brand of thread that is right for the application on my featherweights. I have several different options on my website (
www.thequiltgal.com) for assisting in this regard. The wooden thread stand is my favorite because it is just slightly heavier than the plastic version (which I found somewhere on line and did not work well for me). I also have the springs to go on the thread pin that assists when the spool is too big and flops around. Also I have some others due in after the first of the year to add to my website. Depending upon the size of the spool, different solutions are needed.
