Has anyone ever used serger thread for free motion quilting?
I was thinking that since it is made specifically for high speed sewing that maybe it would work for machine quilting.
The thread I have now is 100% cotton which from what I have been reading is the thread that most FMQ use.

Good question, I have been wondering that myself.

I read somewhere that a quilter used one of those big spools to sew her quilt. When she pressed the top, it melted the thread and it all came apart. Not sure what the thread was - but the big cone reminded me of serger thread. If your thread is 100% cotton and you like the weight, why not use it?

Can't wait to see some answers, as I too would like to know!

A lot of longarm quilters use cotton/poly thread. In fact a lot of the pretty ones are cotton/poly. That is what serger thread is, check the label. I don't like to use cotton/poly thread, but that is just my own preference. I don't usually use the clear nylon type threads in quilting either, but many use it and are happy with it.

So, bottom line is 1) if you like it go for it 2) No quilt police here. :lol:

I have used the MaxiLock serger thread numerous times on my FMQ and I like it. It is 100% cotton and fairly reasonably priced. I haven't had any problems with it even after wash and ironing the quilt. But would be open to other users comments. Someone told me that it is a little lighter weight than other threads because it is meant to be used in combination with other strands of serger thread on the serger, but so far no problems, and it doesn't list a weight on the cones.

I have used MaxiLock too, and it does fine. I've even used it double stranded.
It is a lighter weight than "quilting thread," so take that into consideration when you think how the quilt is going to be used.
But as far as what kind of threads can be used in quilting a quilt, art quilters and thread painters go really wild sometimes in their threads and filaments, and it comes out gah-juss!!

I have used the varigated cone of thread that is polyester and it has stood up well for 2 grandsons quilts that are in constant use for past 3 years it looked nice in FMQ

I used serger threads on cones on my Pfaff 1200 and have not had any problems so far.

I use serger thread all the time.
All of them (bed quilts, crib quilts, sofa quilts, etc) are washed alot and I have never had an issue because of thread.
