I don't know but I will be watching for answers ;D *2U

Hi Gayle, I had problems using embroidery thread in bobbins, now I only use polyester thread, except when I work with FSL.
Here's a link I posted a year ago, it is very informative.

I always use what i call fish line thin ,clear 100 %polyester no.240 i buy from singer it is a spool of 1000,meters for $15. dollars here in Canada oh its made by Skala Carolyn

Strange when I have used sewing thread in my bobbin it has been a disaster (for FSL).
I always match my embroidery & bobbin thread when doing FSL, if not doing FSL I only use bobbin fill.
Maybe it depends on the machine you have? Maybe ask the service person?
Not only that but, boy it would be difficult to match colors of embroidery thread and sewing thread and I think it would get quite costly.

I've used the embroidery thread in my bobbin when doing the applique toweltoppers from smartneedle and there seemed not to be a problem when using. The lady from the Elna store also advised accordingly and she also did not seem to be concerned about it.

Maybe depends on your machine, when I try using sewing thread in the bobbin my stitchouts are terrible, the thread pulls to the top and the stitchout looks awful.

That does not sound as good advice to me, sewing thread being so much thicker than bobbin fill. My dealer told me never to use sewing thread when embroidering.
For FSL I've used polyester as well as rayon embroidery thread in the bobbin with great results.

I'm always told that sewing thread is too thick and too fluffy.and to use special bobbin thread. but perhaps it makes a different hat kind of machine you have?*4u

My dealer has told me only use sewing thread when my machine is in that mode,but i can use embroidery bobbin thread for sewing and it works fine. That is why they are called enbroidery threads because that is what they are made for.hope this helps, cheers have a nice day.

Hi Gayle,

I have never had a problem using embroidery thread in my bobbin. I would call the manufacturer before taking the advise of your dealer.

I only ever use bobbin fill or embroidery thread when embroidering.

I cannot see any reason not to use embroidery thread in the bobbin. I have been told not to use serger thread in the bobbin because of the amount of lint it produces..but even that works if you clean the bobbin area out frequently. As mentioned earlier I would call the manufacturer and check this out. If you can't use embroidery thread in your bobbin it would severely restrict you from doing certain types of designs, including FSL and anything you would want to be reversable. Maybe the dealer was trying to save you from using the more expensive thread in the bobbin when it's not neccessary. Just a thought.

I never had a problem, I have never heard of this but then again I don't know everything either. Maybe your repair man is confused. I would call the manufactor and see what they say. Hope you get some good advice.

Never heard of anyone telling you not to use embroidery thread in your bobbins. Maybe they think you're winding bobbins from skeins. Think your repairman doesn't know what he's talking about as I called mine after reading this and he just laughed and said he thought the guy might be sightly off. I've never had any problems and I can't believe you will either.

I love FSL and always use matching color embroidery thread in the bobbin. I had no problem so far.

I go along with the rest here!!!

Isn't is incredible the amount of misinformation out there? You would think that it would be important to dealers and such to search out and make themselves informed. Here is a site to show you how people have been using quite heavy thread in the bobbin as it's too heavy to use in the top of the machine.

Thanks for all the great information. When I first got my machine I used normal thread in the bobbin ( I didn't know about bobbin fill). The designs where quite heavy. Since finding out about bobbin fill I find the designs sit a lot better. He said that embroidery thread is too strong for the bobbin. I woud think that any polyester cotton would be too strong, even sewing thread. I will be sticking to the bobbin fill. Maybe he was having a bad day. My machines are Brother Snoopy and Brother 750D which is only about 12mths old and the cotton was fraying. The rayon seems to be the worst. I haven't used it since he had a look at it. At the moment I have my daughter and 3 boys here from North Qld. We are waiting to see what cyclone Ululi is going to do. Their home is right where it is going to hit, so it is better to be safe than sorry.

Your machine mechanic is right. I never use embroidery thread on the bobbin. Too expensive and unnecessary, and it can "slip" causing the tension to be upset. Overlocking thread is a much cheaper option and can be used successfully, if purposely designed bobbin thread is not available,(Janome make their own). Overlocking thread can be bought on large cones, generally at a very reasonable price and they last for ages, winding a lot of bobbins. I have 3 colours - white, cream and black, and for most of my designs these are sufficient, as I make a lot of greetings cards where the back of the embroidery is hidden from view. However, these cones are obtainable in a variety of colours, so it should not be too difficult to match up if the back of the design is to be seen. Believe me, embroidery thread is expensive - save where you can.

I always use embroidery thread in the bobbin when I sewing FSL and no problem whit that.

I always use bobbin fill or embroidery thread in my bobbin. In times past have tried overlock thread in bobbin when doing some FSL but too much lint & fuzz from the thread which meant extra cleaning & I was afraid it would muck up my machine. I'll stay with what works for me. *
