I am convinced that threads are especially meant for specific applications. The Superior company, as others have said, has information and a video that is well done. It helps you understand how thread is made and how it should be used. When deciding whether or not a thread fits your budget be sure to check the yardage you are receiving for the money. I like both of the brands you mentioned. I like to use 50 or 60 for piecing and buy in in cones-white, beige and gray. I use a heavier thread size 30 for the top thread when quilting (topstitch 14 needle). I enjoy some of the Sulky threads for this purpose. Therefore, I have a small cabinet of thread. My latest discovery is using Superior Bottom Line thread (size 60 polyester) to stitch in the ditch for stabilizing my quilt before FMQ. I like it far better that the old polyester invisible thread. It is totally hidden. As for basic tools: rotary cutter, mat, a lipped ruler or two. I like some rulers that have multiple functions and steer clear of those that have only a single use. Happy quilting!
