I did end up changing the setup a few times. I eventually had them 3 in a row vertically.
4. I had a window seat cushion that I thought I was going to buy. I never found a lego window seat. So I did the next logical thing and decided to make one myself. I went to a fabric store and decided to buy fabric with legos on it. Unfortunately, they did not have it. So the next logical step for me was to buy Teenage Mutant Ninja Turtle (my son's second favorite theme) fabric. I also bought flat mattress topper foam. I also discovered Stitch Witchery. Maybe I am late with finding out, but I love this stuff!
So basically you place the Stitch Witchery in between your fabric and a damp cloth on top and then iron it a few times until it seals. No need to sew! I ironed it a few times to make sure all the crazy jumping and dancing my son may do on this cushion wouldn't open it.
I also added circles of the fabric on top to make it scream LEGOS.
5. Finally, I placed things around the room with a lego theme. I used an actual box of legos as an end table. I bought a bean beg with Lego Tetris. I used lego bed sheets. I got a lego table with a cover for those days he may want to draw instead.
This may not be the best lego room ever, but it worked for my son. Hopefully, this can give other lego lovers some ideas.
Interestingly, I started feeling sad when I was done. Who knows? Maybe I will put up framed lego posters. As for now, 7,000 laundry loads are calling me. Ta-ta!
