I probably enjoy working with sock-weight (fingering weight) yarn the most of any weight yarn, even though it a) takes longer to knit or crochet, and b) results in a smaller project unless you do a lot more knitting or crochet.
I’ve been working on a sock scraps granny square afghan for quite a while, off and on, and I think it’s my favorite crochet project. You join the squares as you go, not waiting until the end, and the last round in each granny square is the same light gray yarn, so there is a cohesiveness to the design.
I added 6 more squares yesterday. Each square takes between 3-4 grams of sock yarn, so it’s great for leftovers from all those socks and shawls and mini-skein packs that are so hard to resist.
I originally wanted to make this 15 wide by 20 long, but I may revise that and make it slightly larger, depending on on how it looks and feels when I get to that point. One of the nice things about this project is that you can keep going or quit when you arrive at the size you like.
Attic 24 posted a great join-as-you-go tutorial a few years ago. She has quite a few crochet tutorials if you’re interested!
Not too long ago I started another sock scraps yarn blanket called Variegated Ripple Scrapghan. Here is my latest progress. I’m going back and weaving in all those ends before they get to be a much larger task!
Once again, I’m using sock- and fingering-weight yarn scraps and minis. This one takes a bit more yarn per row than the granny squares, but still not much. I decided to go with a bit darker color this time to bring everything together. It really makes the design pop.
