I have shared a lot of what I have been knitting for our new grandson. Here is a sweater that I designed and knitted for him. I used a very soft wool for this sweater and made it to fit, so that he will probably be able to wear it as a coat all through winter, until March.
I used every bit of the ball of yarn that I had. My scarf isn't a real long scarf, but it is a great length and I will wear this. AND more are in the works, too. If you want to make this scarf, here is the link to the pattern.
My yarn was a bulky weight and I used a size K (US) crochet hook for it.
