I do like glazed cotton thread - Gutterman at JoAnn's is ok, although, I prefer YLI and i have to order it (YLI is the cheapest when you pay attention to the yards on the spool)
One of the reasons that I like the cotton batting is because of the little bit of resistance when putting the needle thru - it gives me time to get my stitches where I want them. My stitches aren't as consistent w/ the poly battings because the needle "falls thru" the quilt. Another reason why you try all kinds of different stuff out - to see what you like best.
