A few of us knit and/or crochet hats for our local AT&T TeleCom Pioneers chapter. It started as a Caps for Kids project over a decade ago and now the caps go directly to City Union Mission. I've finished 5 hats/caps this year toward my goal of 48 hats.
This cap was knitted from the top to the brim. I had a partial skein of variegated yarn and I wanted to use as much of it as I could. I hid the change to the solid avocado under the brim.
I call this a cap of many colors. I probably had less than 2 ounces of black and combined that with leftover bits of other colors to make a striped hat. I call the pattern a Formula Hat. I've yet to write down the pattern, but with the basic formula you can make a hats with different yarns and in different sizes.
This is a Spiral Skull Cap. It's half double crochet with front and back post double crochet. I used a wee bit of the varigated left from the knit cap above at the top and then switched to the avocado. This is an unpublished pattern I've made for a few years for charity. It's pretty quick to make.
I added some terra cotta and brown to the last of the avocado and made another striped Formula Hat. I used every last bit of those yarns.
This is another cap that I knit top down. I wasn't sure how far the light coral would go, but I knew I had plenty of the light coral and orange combined. I added a band of seed stitch to add some interest.
The contents of the drawer below have inspired me to make these scrappy hats. I have other yarn to make hats, but I'm in a bit of a clutter clearing mode right now.
