I prefer thinner thread for piecing and for SITD quilting, but for quilting or topstitching that I want to show up I love CT thread. Yes, it's lintier than premium thread like Aurifil or Presencia; but it's good sturdy thread and the price is sooo low and color selections are great. I waited for a sale and (literally) bought at least one spool of every single color!
Buy a spool, try it out! I'm betting you'll like it. And while you're shopping there, get yourself a pair of their little purple-handled snips. I LOVE those little scissors and buy a pair pretty much with every order because I keep finding new places I want to keep a pair.
I've actually seen a quilt shop selling spools of Connecting Threads cotton thread, it was marked up to $8/spool. No idea if it was selling or not, but I had to laugh at that. I'm not sure it's worth $8/spool, but it's DEFINITELY worth the $2-3 on the site.
