Substituting Yarns

Can I substitute Brooklyn Tweed’s Shelter for Rowan DK Tweed? Or Miss Babs Yowza for Rowan DK Tweed?
Please help! Thanks

Hi Chimayo,
This site might be helpful. Plug in the yarn, and it will tell you the best matches.

Thanks - you’re about the third person telling me about this great new (to me) website. I’m sure it’ll be very helpful.

Thanks for the tip - others have suggested it, too.
