I have been given a sample of Gutermann 100% cotton thread on a cone to test on my HandiQuilter Longarm machine.
I have used Guterman threads for as long as I can remember on my domestic machine but not used it on my longarm until now. I will be upfront and honest here and say that I don’t normally use cotton threads on my longarm as I find them really linty as they run through the machine at a high speed and can on occasions snap quite easily.
Having said that on the machine went the cone of red thread (Col 2074) and a scrap piece of calico and I began stitching with the machine in regulated mode and found the thread to behave beautifully, creating good stitches. So now for a bigger test. I put it into manual and set the speed of the machine at 75% of its maximum. I was surprised to find that it still ran very well and stitched really nicely. So nudge the speed up more, and it was still the same.
I stitched for about 20 minutes altogether with the thread and after a while it was obvious that lint was starting to build up, as expected I have to say because it is cotton. However the stitches continued to be good with no breaks, even at a very small size stitch or long stitch.
This is the lint gathering around the hopping foot and from inside the bobbin area after that 20 minutes, which means you would have to clean the area on a more regular basis, but you need to do that with cottons anyway, its just one of those things we have to put up with in order to use cotton thread.
Would I use it again? Yes I would when the project calls for a cotton thread to be used.
