I was working on stretchy knit fabrics and I needed to finish the hems of a T-shirt with zig zag stitch on my vintage sewing machine since I don’t have a coverhem machine. I needed navy blue thread and I did not have any. Went through my thread organizer and found tons, I mean tons of serger cone threads and I found the one navy blue color . I wondered how I coud fit a serger cone thread on my vintage sewing machine? I searched for ideas over the internet and I found that you can use a winder to transfer cone thread to a smaller spool of thread. That seemed too complicated so I discarded that tip.
Another way that you can use cone thread on your sewing machine is with a cone thread holder, place it next to your sewing machine and thread as usual.
I liked this tip a lot but I have so many gadgets and I just needed to sew very little so did not want to spend any money on notions. Maybe in the future. Will put it on my wishlist.
Then I found on Quilting Board a useful idea: One of the members suggested you can insert your serger cone thread into a thicker sewing machine spool thread. I looked for my threads, and found lots of Guttermann’s textured thread (“wooly” like for serging and stretchy fabrics). So that did the trick!
This is the thread I used: Gutermann’s textured thread. This is a picture showing the thickness of the spool thread and how I inserted the Maxi Lock cheap serger cone thread on top.
It fit like a glove on my Singer 401 sewing machine. I could sew without any issues. I have read mixed reviews. It would depend on what kind of sewing machine you have, the thickness of your machine spool pin and spool thread. So you could just test out and see how it feels.
