I found a darning needle recently and I was able to finish up the experimental knitted checker board game. I didn't have a pattern so I had to improvise on the entire project.
I simply used bulky yarn that I had in my stash (I didn't have red, but I like the brown and black). Using size 10 needles, I casted on 36 stitches, and did 2 rows of garter stitch. Then each odd row thereafter was knit 2, knit alternating colors every 4 stitches, knit 2 at the end. Each even row was knit 2, purl the same alternating colors every 4 stitches, knit 2 at the end. Every 5 rows, the alternating colors need to be reversed. Make 8 sets of 5 rows (40 rows) and then garter stitch the last 2 rows in black. Cast off and tie in the loose ends.
For the bag, I used magic loop (double pointed needles work well, too). I casted on 36 stitches and knit in garter for several rounds, switched to stockinette for a few rounds, then continued in stockinette with brown until it was long enough to house the rolled up checker board mat and rock game pieces. I knitted 2 together and knitted one along the entire round to make 24 stitches now. Next round, I knit 2 together all the way around to yield 12 stitches. Then, I knit 2 together all the way around again, leaving 6 stitches. I pulled those tight, pulled the bag inside out, pulled the excess yarn through and tied in all loose ends.
For the rocks, I simply gathered several, painted them black and brown, and put them in a muslin bag with a yarn tie. Note ~ Flatter rocks are preferable because you have to be able to king your opponent.
