My machine will only use, i know this is nuts, but it's a very old machine, it will only use the wal-mart 3/1.00 thread. I know, the cheap thread is supposed to be the worst for your machine, but my machine i guess is too old to know the dif. Can't remember last time i've changed a needle, maybe 3 years lol, but it really really does work great lol lol I dont know if i've ever oiled it, seriously, and hmm, to clean it, lift the needle plate and give one strong blow lol lol 40 year old kenmore lol

I use poly/cotton for my Kenmores and it does fine. My older Kenmore does not like cotton! I have to clean it every 15 minutes or it nests up if I use cotton.

Now my Bernina is ok with the cotton. Go figure.

I like to use Gutermann and Coats and Clark

Thats exactly the same with my old kenmore! It doesnt like cotton, interesting lol

I've been using Mettler because that is what is available at my local quilt store. They have tons of fabric, but the thread is very limited. I do have some lint but not copious amounts. I have the Babylock Ellure which is computerized and so far have not had any problems using the Mettler. I would like to experiment with other options though. The aurofil sounds interesting.
