I was advised to buy good thread when I took quilting lessons and in workshops since. I've been quilting with Gutterman thread, but even it is rather linty at times. Just about two weeks ago, I ordered a sampler pack from Superior Threads. Many of my quilting friends swear by their thread. My logic is that if I don't seem to have any trouble putting $150-$200 in the fabric for a quilt, I shouldn't complain if the thread is a little pricey, especially if it will work well with my sewing machine and is known to last. I've never used an entire spool on one project either, so perhaps you can get two or three from one spool.
