Hi!
I wonder if someone could help me. I'm looking for specific thread to buy but I don't know its name and I have no idea where to look for it.
What I can say about it: It's a little bit thinner than embroidery floss, looks like craft thread but it's very slippery, knots are easy to undone. It has very intense colours and it's shiny.
Looks like this:


If anyone knows the name I'd appreciate that. If some of you buys that type of string on the internet, please share a link for auction on aliexpress, ebay, allegro etc. or tell me what do you type in search bar ;)
Thanks in advance! :)

I'd say Pearl Cotton if it's a cotton thread. DMC has it in different sizes, thicker but also also thinner than floss.
It could also be nylon though....

You could also take a look at DMC Satin or YarnArt Tulip
