Compared to knitting, crochet is easily a "less-favorite" craft. It can be fun for making amigurumi which are usually pot-bellied and adorable, and I did make a pretty cute summer dress, but it's not my go-to craft by any means.
However, there is one thing that crocheters can make that knitters can't really replicate. Granny Squares.
I know some people think granny squares are tacky (and they kind of are) but I love the way they look. Recently I picked up 200 Crochet Blocks and started picking out blocks just to experiment/brush up on my skills. The yarn is cheap-o Red Heart mostly because it's cheap and machine washable so cat-hair accumulation won't be difficult to deal with. I'm using a pretty big hook (size K) so my blocks are coming out about a foot square. I bought 4 skeins, the three colors you see above plus a burnt orange. I'll make blocks until I feel I have a sufficient number for a good cozy blanket or I run out of yarn.
My holiday knitting has put this on the back burner for a bit (probably until after new year) then I will pick up the hook again. I really enjoy making these since each one is like a mini project in itself and brings its own feeling of accomplishment when finished.
