Recently I posted a small video on Twitter showing a shiny QGIS sticker I made and I got the the question where I ordered these. Because a blog is easier to answer that question then Twitter, I’ll tell here.
I took the QGIS logo from the QGIS Visual Style Guide and used Inkscape to create a modified version. I wanted the Q to be white because that would be the most shiny part of the sticker, but I added a small black border. For the background I used the green #589632 from the QGIS Visual Style Guide. Then I created a small green buffer around the Q.
I ordered the stickers from Sticker Mule and because I only needed a couple of stickers, I ordered their “Holographic sticker samples” using my own SVG file. They cost €8 for 10 stickers (76mm x 76mm). If you want more than 10 stickers for your FOSS4G or QGIS User Group event, you can also use their general “Holographic stickers” offer.
