I've just upgraded to the new Singer XL6000 machine and was wondering if anyone has had success with specific threads with it. I have been told that I should use Robson Anton but I have quite a bit of thread from my old machine that I purchased on ebay and would like to be able to continue using it but not if it's going to be a problen with my new machine. If I do have to use this brand does anyone have a site address where I can buy in bulk, all I see in the stores are individuls spools.
