I purchase large cones of thread by American and
Efrid. The thread is made in America. I try to buy American as much as I can. It is the same thread that I use on my longarm, it's size 30 and 6000 yards and I think it's between 7.00 to 10.00 a cone, I forget now. I have lots of colors. I love it. I dont' buy any other thread. This tread is not waxed and is strong and all my machines love it...I have a Janome, Bernia, singer feather and a quilt series brother....
I don't believe in small spools of thread. I sew too much and buying those, save me pots of money.
