I’ve designed this pattern as I couldn’t find quite what I wanted - coasters for an adult gamer with a fondness for this Japanese graphics game.
I used a standard flat circle pattern and adjusted the stitches for the different rows to get closer to the look of this gamer’s ball.
You only need oddments of yarn, even for a set of 6. My DK cotton was from different manufacturers which was unfortunate - the red is heavier than the black & white and it shows in the photo.
