I Got some silky pinkish yarn in a grab bag I picked up and I wasn't sure what it would be but wanted to use for something. After several test knits I decided to pair it with some thin but textured white yarn I'd gotten a while back. I also got a size 15 9" circular needle in my grab bag so I cast on 100 stitches with that and decided to make a hat. I knit around the whole time and decreased once it was seeming long enough. I had a bit of a challenge casting off using just the 9" circs but managed to figure it out after discussing the issue with knitting buddy :-)
I tend to have issues with gauge so my hat was quite large around the "brim" part, so to fix that issue I knit up an I-cord out of just the pink yarn and then sewed that on while scrunching up the brim a bit. It now fits perfectly! I had originally planned to add a flower on it as well, where the I-cord was joined, but I was too anxious to wear it and now it doesn't seem as necessary...
