I plan to display some creations at Brick 2015 in the UK. This will probably be the first display at a LEGO convention as well as purchasing specific parts for MOC's. I normally build on LEGO Digital Designer and occasionally build with actual bricks, examples can be seen here:https://www.flickr.com/photos/[email protected]/sets/72157645785522606/
Now for your help! I need to know what is the best way to purchase parts for LEGO MOC's, I plan to display some of my best creations that you guys have already seen as well as some new secret projects. What is the best option or cheapest way to build LEGO MOC's? Pick-A-Brick, buying multiple sets, Bricklink/Brickowl etc. How do you guys plan in advance?
Any other tips and ideas you guys have to help me with your past experiences of LEGO conventions and building MOC's?
