What is the name of that site for yarn substitutions?

It is right on the tip of my tongue and won’t go any farther:wall:. I am looking the site that you can find out what the a yarn is (DK, worsted, etc.) by finding the name of the yarn on the site?

Can someone remind me of what it is please?

Are you thinking of Yarndex.com?

Do you mean Yarndex?


YES to both of you! Thank you!

The only thing thats bugs me about Yarndex is that is never seems to list the yarn I have or am looking for LOL!
