I'm looking for good quality thread for blanket stitch edges and simple lines but in a shimmery, sheen silky quality. I have some very poor quality, maybe it's cotton, I got from a local cheap shop and it's so annoying as the fibres keeps getting separated and tangled up as it goes through the needle into the fabric, if you know what I mean. Anyway, there are no suitable shops near me, so any online suggestions will be welcome.
