Texture it, and line it up.
Three ridiculously highres images you can use to help create a griptape mod.
Created in paint.net using Noise Tool, circle tool, etc. Rethawed and THPSHD grips used as reference. I tried my best to line up the bolts with the truck bolts on the preset THAW X360 board.
Keep In Mind
Transparency works for griptapes (slicing designs)
When finalizing your design, try exporting at a resolution of 256x512, or 256x1024. The resolution of the provided images is probably way higher than need be.
