OK maybe a stupid question but is there an easy way to find out if your thread is too old to use besides the dust ect. Like if tugging at a length of thread..if it breaks easy it's no good? I ask this because I have several bags of threads DH bought for me at Estate Sales. How do I know if it's too old to use? TY Quilting Board for all your excellent advice.
