I'm going to be a dad! But..

Having a baby boy in July, need to clean out my Lego room.. it is in this moment where I realize how much Lego I have! (Modulars, Star Wars, Castle, Pirates and many more..) Anyways this is going to be my project for the coming weeks 😆 Any tips to pack it all up are welcome! Currently went to IKEA to pick up a bunch of these plastic bins. Its all going on the attic (it should fit, right?) until I'm able to rebuild my garage (needs to be isolated and probably enlarged) this is probably 1 or 2...
