I crocheted the bottom, and made it bigger than the one in the pattern photo. That one turned out kind of small. Here's what the bottom looks like on the finished bag:
After picking up the stitches around the circle, I quickly realized why a variegated yarn isn't good for the bottom of the bag..... Here's what the rest of the bag looks like:
The colors on the crocheted bottom are in blocks, due to the way double crochet works. Then the stripes on the body of the bag are from knitting in the round. I was dismayed, but I still love this bag! As you can see, I ran out of the variegated wool before the bag was tall enough, so I finished it with a denim wool, from the same company. I believe it was Patons Classic. This bag remains one of my favorite project bags, even with the weird color splotched bottom.
So, dear readers, my advice to you is if you choose to make this bag, save your variegated wool yarn for the body, and use a solid color for the bottom! And remember, you can make the base as big as you want, and the body as long as you want!
In all actuality, the bag in the pattern photo is kind of small for my taste. I've made all the other ones bigger. And this bag would make a cool purse, just get a magnet or some other kind of clasp and use it to connect the long sides together.
