I sorted the Lego by type rather than color as this suits the way we create, but it is up to you.

To make the labels I used Lego Digital Designer which has the command "take a screenshot" then paste it into a graphics program (even Windows Paint will do). Print them out, laminate and cut each label 90x25mm.

Overall I am happy with the outcome and I feel I covered my criteria well. Most importantly, my son loves it.

Thanks for taking the time :)
