Did anyone's parents help you make some Star Trek toys?
My mom had a pattern for costumes and made them for my brother and me when I was in 3rd grade. My dad phasers and communicators to complete the look. I actually found the same pattern online and my mom volunteered to make me an adult costume a couple years ago for Halloween. It's incredibly accurate - better than any of the retail ones I've seen.
I also built bridge and engineering TOS playsets out of cardboard when I was younger. I matched the size to the action figures and paused the episodes to make sure everything was as accurate as possible. I could never figure out how to add aux. control to the set though. haha. All in all, I spent many hours making everything just right. Great memories!
