In her Friday Finds, Alice C linked to the Spruce’s post of DMC to whatever (& vice versa) thread conversions. It’s really really useful & one you should bookmark, especially if you’re on a budget & can only find/afford DMC. I will second their comment regarding converting Weeks Dye Works to DMC – use two different DMC threads to get a truly unique piece of work.
