I was ruminating the other day that a guide to yarns would be helpful so I could choose the right yarn for my project. Viewing the scarves being created on the ISE blog, I realize now just how important matching the yarn to the pattern can truly be. Trial and error is fine in many cases but there is a limit to the number of times I'm willing to swatch! So far I haven't found one. The up side of this is that it leads to many interesting conversations with experienced knitters and crocheters.
Then on a yarn crawl today I ran across a resource I didn't realize I needed until it jumped into my hands. This pamphlet is a yardage guide for a variety of crocheted items so you can purchase the right amount of yarn even if you don't have a pattern yet! What a great idea! Needless to say I purchased one. :0)
P.S. Knitters - there is a version for knitters too!
