There is this online learning tool called Craftsy. They offer many types of classes in a great format. Some of the classes are free but the more involved ones have a fee.
I've taken several classes. Rigid heddle weaving, spinning dyed fibers are two of the paid classes that I've taken so far.
Recently I signed up for a class by Icelandic phenom Ragga Eiriksdottir called Top Down Icelandic Cardigan. Check her out here. http://www.ravelry.com/designers/ragga-eiriksdottir
I'm obsessed with the pattern and the class. I'm not using the recommended Lopi yarn. I'm using Berrocco Peruvia which is very similar to Lopi in my opinion. I can honestly say that I could probably knit this pattern without taking the class. There aren't any new to me techniques but there is just something about knitting along with Ragga that is so enjoyable.
I knit the yoke up lickedy split. I chose a cream colour for the contrast and a deep chocolate brown for the main colour. There also is a tiny amount of a 'pop' colour used. For this I chose a bright blue. I love this combination of colours.
I'm currently at the point where I've already separated for the sleeves. From here on out I'll be knitting with the brown only. While this may get a little boring at times I want this sweater so badly that I really think I'll push through.
I'm actually looking forward to the steeking believe it or not. And I've already ordered buttons. That's how much I need this sweater. I should also order some gros grain ribbon. Ragga goes over all of this in her class. The steeking, the sewing on of the grosgrain ribbon, and even crocheting the button loops.
I've already watched the class straight through. I rewatch each section as I get to it on my sweater.
