Thank you to all who responded. Wow! so much to learn and research. C&C was the only thread readily available so that why I used it. After reading all your comments, and they are very helpful, I think I'm going to try a thread set from CT and then a Try Me Special of a couple of different threads from Superior, Aurfill is also high recommended here so I'm going to order a spool of that too. This is exciting. Different machines like and don't like certain threads, so when I find a thread that works well in my machine and don't have any troubles with it I'll stock up. Thank you all again for your wonderful wisdom and advice!
