Hi Quaking Plums,

Our mousepads are high quality and the fraying is not really a problem, however we would recommend stitching for peace of mind because no matter what mousepad you buy it will fray eventually. We have 6 stitching colours to choose from!

Find detail comes out really well, you might know already but sublimation and DTG are the best textile printing processes for quality. Since it's a dye the print is also permanent with no fading so washing it like you would clothes is perfectly fine.

We recommend 300ppi. Regarding the question you asked 'Did you use the integer scaled version of this canvas or is it linearly interpolated?' We have no clue unfortunately, our customer provided the image.
