I do not quite understand. I have just embroidered some FSL snowflakes with siverthread in the middle. Looks great and no problem. I rinse out in cold water. Leave it for some 15 minutes. that leaves some in to keep it stiff to hang up.
I slowed the machine right down for the silver thread

I always mix my threads in fsl. Metallic thread works out fine. Use a 14red tip needle or a metalic needle. You can rinse in warm water to disolve stabilizer it will not damage the metallic thread.

Hi Modo, I've done many fsl with metalic thread and rinced them is the very hot water without any problems!! Good Luck

Michelle, I have never had any trouble with it - with my FSL. I love the metallic thread to work with. *4u

I too, dont have problem with the metallic thread and heat. I have problem stitching with them :)

I too have no problems rinsing out with hot water. Or ironing embroideries with metallic. I either use Madeira, Brildor (a Spanish product) or a metallic I bought at a large embroidery studio; that large 5000m cone does not display a brand name, but it's the best I've ever had.

I love adding metallic thread to my FSL designs, especially Christmas designs. You just need to know when to change over to the metallic thread as you don't want to try and stitch very dense sections with all metallic.

I will often take a design into Embird Editor, run it through the stitch simulator several times until I can see which stitches I want to be in metallic, then I will split the design into sections and change the thread colour so that I can stop stitching at the precise place I want to change to metallic thread. This makes it so much easier than trying to do it at the machine.

I have had no problems rinsing in hand hot water, and I iron the project on the wrong side, or will use an ironing cloth on top, to avoid problems.

I haven't been couragous enough yet to do FSL,
but I take note of every advice you give in a notepad file which I save in my "advice" file. I can never find the info when I do a search on any site !
I'll be ready when I try the FSL.
Thank you to all.
