Hobby mat themed desk pad (with accurate measurements)

Wanted to share an idea I put together for fun. Maybe there could be enough interest out there to warrant doing a small group buy. The Desk mat design is based off of the standard size sold by NK, measuring 400mm x 900mm. I made 3 versions of the design in white on green, blue, and black. I took into consideration adding yellow lines as a variant to the white, but I didn't want to give too many options and muddy the decision making, however I am not completely ruling it out. The measurements in the design are accurate, and could be actually used to measure on your desk. there ae markings for inches and centimeters. Let me know if you are interested or have any suggestions!
