What do you do with all the empties?
Do you get credit for them?
I hope they don`t get thrown away!

I just throw mine away.
I've never heard of trading the empties in.
I'll be watching this thread!!

I reuse the plastic prewound bobbins that I have bought, but if they get too many burrs on them my machine won't stitch correctly and I have to toss them.
I try filing them smooth first, but it doesn't always work...

I buy the cardboard ones so I can throw them out.

I never thought about buying them because I have tons of bobbins here and the fact I use vintage machines exclusively. But this has been around for decades they used to sell the bobbins for the Vibrating Shuttle machines pre-filled. (the barbell looking ones)

It is a neat idea but it does seem like a waste to have a plastic bobbin that you can not turn in. Seems like with all of this "Go Green" thing that they would offer a deposit on them like the old glass coke bottles. (Remember picking them up and turning them in for candy and comic books?)

I take the cardboard off the thread before I put it in my bobbin case. I toss the plastic ones, the plastic is so thin it doesn't hold up for rewinding and using.

I use the cardboard ones in the embroidery machine.

I only use the prewound with the cardboard sides that you remove. I have to sometimes really think on how to wind a bobbin when I need another color. LOL

I have Bernina Machines and the manufacture says not to use pre wound bobbins.

Just recently got a pkg of plastic ones and got them mixed up with my regular ones. I usually only use the ones with cardboard sides or wind my own.
