I have a singer 201 (circa, 1947) sewing machine and want to know what is the heaviest thread that I can use to sew 4 ounce (1/16 inch thick) together.
I would like to #92 and if you have some insight thanks. If so, I think the 110/18 needle would work. If you recommend only #69 thread, should I go with the #16 needle? Most that I've seen online says most home sewing machines max out at #69 thread.
Thanks,
Reid
