Thanks for posting this thread Megan, until about a year ago I didn't know there was much difference in thread or types, except when I took my first class in quilting. The teacher said to use 100% cotton cloth, and all cotton thread when using 100% cotton cloth. Last year someone had some comments on thread types and that is when I discovered there were differences other than price and content.
I have a whole new perspective to learn about thread now.
Sorry for those who are out of work. I have my job which is good but less time for things I'd rather do, but the job allows me to have some money to do things with. Our wages are essentially frozen, we get about 2% raise, but contribution costs to insurance goes up about 4%, and parking is also up about 4% per year, so we are sliding in the wrong direction.
