I like to use Gütermann Thread and I’m sure the great quality of this product has kept my machines in good working order over the years. As the last stockist near to my home in the UK moved recently I was scratching my head as to how I was going match thread to my fabric online. I did a quick search for a colour chart and found one online at Sew Essential. I would love one for the silk thread too but at the moment I can’t source one.
I’m planning to go through my stash and note the matching thread for each one, that way I can order them all at once and save on postage.
