I hope I am posting this is the right section, if not I am so sorry and hope someone will let me know.
I was recently gifted with about 20 spools of size 2 thread. This thread is to thick to go through the eye of the needle of a regular sewing machine. I have a heavy duty Consew commercial stright stitch machine but the thread is also to thick to go through the eye of the needle on it . Can someone tell me what type of machine uses this size thread? Is it possible to buy a needle with a larger eye to fit the commercial machine? If so, would I use the size 2 thread on the top portion of the machine or would I use it in the bobbin? Thank you in advance for your assistance.
