Threads & Rotary blades
Depends on what I'm doing But I never use Coats & Clark it doesn't work well with my machine it breaks. frays, a lot of fuzz. It jams my machine. King Tut thread is good I also like Madeira & Gutermann.
I've used a lot of different rotary cutters I'm left handed so some don't work well for me. How ever in Sept I purchased a Gingher Rotary cutter I just LOVE it. It is like night & day. It cuts clean & easy on the hand. I have arthritis.
