I used plain old sugar n cream yarn and broad cloth to line it. For the pattern I just chained I think 30 then single crocheted across putting three single crochet in the last stitch and turned to work in the extra loops of the beginning chain. I just kept adding three single crochet in the middle stitch on each end until I had it the size I wanted then just kept single crocheting around changing colors every two rows.
To finish it off, I took a strand of brown and wove it through every other row or so before lining it.
So I basically just made it up as I went along.
