Old sewing thread
I went to an estate auction today and picked up an old sewing stand. It has several spools of thread inside. I assume that wooden spools would no longer have useabe thread on them. I would further assume that thread on sterofoam spools would no longer be useable. Is this correct? Now I would like to know how to tell if regular plastic spools contains useable thread. Just because it is on plastic spools probably does not mean it is good, fresh strong thread I also assume. So how can I tell before I put it on my machine ??? That Ks in advance for your help. Sue
