I mentioned in "Main" section about having some old "The Workbasket" magazines. There was an article about a lady who embroideried on her machine.
Later in that same article it mentioned that she mended silks and woolens on her machine,,,,,using human hair!
She used it for frayed material, snags, moth holes, etc, tying the ends together like you would any sewing thread. Evidently, if you are patient enough, you can have enough "thread" to put on a bobbin and use it on your sewing machine. No attachment is used, feed lowered, and you can weave by moving the cloth back and forth.
Don't know if that will work on our modern machines or not, but if so, this is an answer to the thread problem....
