      Legos mean love around our house. :o) I'm off to check out some of these links...

      Thanks for organizing this, will make it much easier to access. Just introduced lego building to a small group of autistic kids I work with and they love it! Thanks for being a source of inspiration!

    3. Y Jan 20, 2016

      I love this collection of Lego inspiration. Thanks so much for sharing all your creative ideas!

      Here's a question: what Lego sets did you start off with? We purchased a large classic set and have a bunch of one-off Ninjagos, but I am not finding the assortments as versatile as I remember them from my childhood.

      1. JR.M G Jul 9, 2020

        I think they had a ton of legos and then they just built things with them. They don't look like a set to me

    4. Zachary Lopez Jan 22, 2016

      Awesome! Thank you so much.

    5. MarickH Sep 16, 2016

      Wow. I have just discovered your site. It's amazing. Thank you for sharing these!

    6. Rachel Goodman Aspler Jan 22, 2017

      Hi. My son loves LEGO and we've decided to use it for his theme for his Bar Mitzvah. He will be building the centrepieces. I want him to build the table numbers out of LEGO or picture frames. Do u have any instructions for either of these? I've found online but they're for very simplistic (juvenile) designs. Thx

    7. Alice Hauser Aug 23, 2017

      Are the pets in either of your books?

    8. Josh Feb 2, 2018

      Wow! Great website - thank you so much! I work with youth in Vancouver, Canada , on a project that collects used Lego and donates it to less-privileged kids in other places around the world. It is awesome to have a website that we can direct those receiving our Lego to, so they can enjoy the Lego to the fullest!
