So, what to do with leftover yarns? This is an idea. I had different off white yarns leftover from other projects. There wasn't enough of any one particular yarn to make a whole project, but, put together, they would be enough to make an interesting cowl. I did it in garter stitch (what could be easier?) and then joined it together when I thought it was long enough. But when I finished that, it looked too blah...So, what if I were to crochet some flowers of different sizes and put them in a straight line. That jazzed it up. But it didn't seem like that was enough to make it pop. So, I decided I had enough of one of the yarns to put a fringe all around. And that did the trick.
I wear it either with or without a pin. It really looks sharp, and because the yarns are complimentary, and off white, it really does go with anything. Of course, it can be made with any color of yarn, or you can use different colors of yarn to create a color block cowl -- I think that would be really sharp. The only thing I would recommend is that the yarns be of similar weight. But then, that is not a rule. Rules in knitting are made to be broken. Make the project your own and add whatever flourishes look good to you. That is what makes inventing and experimenting fun.
And the results can be stunning. Have fun.
