Lego building as a hobby

Christmas usually starts a solid 2-3 weeks of me building legos. BUT, I think this is the year that Ive taught my boys the lego building process to the point that I can stay out of it and let them rip. Grandparents gave them both bigger sets for Christmas. My oldest son just finished the 3600 piece Nasa Artemis, and the younger built the 3300 piece Medieval town square - with zero questions between them.

I know they have more coming, so here is hoping that this is my first lego free Christmas in probably 20 year.

Although, I honestly do like building them. I think either the Saturn V or the smaller of the 2 millenium falcons were my favorites to put together.
I'm quickly running out of space so having to be more selective in what I buy. I love space amd Star Wars themes. Artemis and Saturn V are definitely on my wish list, but probably will be a while before I have room for them.
