I am not especially new to knitting, but I have never really branched out much from scarves/hats, and have always just made things up based on what I had on hand. Now, however, I have my heart set on Knitty's Candy sweater(http://knitty.com/ISSUEwinter04/PATTcandy.html
). I need advice about how to find the right yarn online. I have spent time browsing various sites, but just wind up confused.
I can't find the brand that is listed in the pattern, but I have a feeling I wouldn't be able to afford it even if i could. What is an easy way to know that another yarn will be a good substitute? I know that the gauge listed here is 18 sts/25 rows = 4", but how do I know what category of yarn that is (ie: worsted, etc)?
The internet can sometimes be totally overwhelming: thanks so much for y'alls help.
