These knuckles come courtesy of Tiina K. of Finland. Here is her story:
I had dreamed about knuckletattoos for quite long, but I had so many options and didn’t really know which one to choose. Suddendly my depression got a bit worse and I went through a difficult process with getting to know myself. I’ve always been a social and loud girl, and talked alot. Yet I noticed a change in me, I had become very shy. I took words “Live loud” to remind me of being proud and brave, and leaving behind that quiet mouse I was. I chose this font cos I’m a huge fan of oldschool tattoos and especially sailor tattoos. That’s why I chose anchors for my thumbs also.
