I got an email from Connecting Threads today. They have thread on sale. I am going through thread like it's water. Sometimes I have some pretty crumby stitches, so I figured it's the thread. So my question is......The Essential Cotton Thread they have on sale in sets of colors. Can that be used for piecing on a machine, as well as quilting. I'm fairly new to machine quilting, and I have a ton of hand quilting thread that I know is just to thick. So can I use this at $2.19 for 1200 yds a spool, as compared to Hobby Lobby $5.15. Or is there something else I should be using. I'm quilting up a storm, but not happy with all my stitches. Almost all my fabric is cotton, so was just wondering. I'm spending more on thread than material.
