Youtube is a platform that I like to use to share my build and collection and take people through how I build things so that they can hopefully take some inspiration from that into their own builds
As I take a lot of Photos of my collection in and out of set settings, I need a place where I can share all those photos with people who already know my work and people who don't. That is where Instagram comes in because it is a platform I can use to share my work with my existing audience.
Bricklink is an online LEGO Marketplace where users can by and sell individual parts, sets or minifigures.
