I think this is a weird category to put this in, but this is hardly papercraft.
Here's the ready-to-print bookmark for my Squashed Twilight vector. Recommended for a width no wider then 4.5cm/1.8in for printing. Updated so it's gamut friendly and Twilight's purple won't be off when printing.
I made mine by printing it out, sticking it on card, laying a strip of cellophane tape over it and then cutting it out directly along the vector's edge. You can see how it turned out here: [link]
Enjoy! And thanks for the love on Reddit r/mylittlepony [link]
