Yarn Comparison Chart

[Deeknit]

Hello, I'm new and love this site. It is a great reference.

Now, I would like to find some sort of chart comparison of yarn brand equivalents. Is there such a monster?

Example: How to I learn what will substitute for Berroco HipHop if my local yarn shop doesn't have it? I know she can help me, but i would love to have a chart reference.

Thanks for any help.
