hi I know this is probably a really old post hopefully it's not had a few questions and since you said you are working with boat upholstery / canvas umbrella work I myself am doing the same thing and I'm quite new at it. So it may sound stupid but you said that you use its narrow thread is that the lifetime thread that you were using and the size needle I'm not really sure about needle sizes and what you can use exactly with which type of thread should I be using a #14 like you were saying.? Is there anybody on this that can tell me if exactly what type of needle I should be able to use with the Tanera lifetime thread?
Thank you
Heather
