I used it with mulin and frayed such that the wire unusable, I came to doubt that will work only with the sewing thread xRating: [3 of 5 Stars!]
Hello dear Robi67, in fact, these needle threader are primarily designed for sewing threads, or the sewing threads ... But also counts the measure of \ 'needle, of course. In case you want to still continue to use it even with the moulin I suggest you choose needles not too thin and maybe pass the thread in this product: http://www.casacenina.it/adam-beadworks/thread-heaven-condit-
ioner .html which makes it very smooth and \ "slippery \" without anoint No stain, and protects it from fraying. Best wishes.
