The second floor continues with the finishing touches for the lighting, signage, and windows. At this point, everything is relatively simple; you just need to install the lights according to the instructions. The important thing is to pay attention to the joints; using too much force will cause them to break.
It’s looking so great already! Totally agree about being gentle with the joints, slow and steady is key with this kit. The sticker idea for the chair joints works surprisingly well too. Can’t wait to see it finished, you’re so close!
