This is a chart for a pac-man pillow I made up for an 8-bit swap. I used a cross stitch/charting program and eye-balled from some pictures.
I worked it in Tunisian Crochet making sure to twist the yarn as I went. Watch this tutorial by GegeCrochet
I don’t remember what my gauge was but it ended up being small throw pillow size when I was done.
If you want to make a throw pillow like I did, you follow the chart and then stitch three and half sides, stuff and stitch the last half.
You can use the charts for whatever you want, they are pretty versatile!
