A little late for Mother's Day, but this model may be helpful to show her how much you care (and hopefully get you outta the doghouse if you're there)

This project utilizes ElectroLuminescent wire (2.3mm) widely available on Amazon or other outlets. The tray is optional, but helps keep things organized. There are two holes in the base of the wall to allow feeding the wire through and back in at the end. Unfortunately, it can't be scaled, as the slots for the wire would become to tight or too loose.

I hope you enjoy it!
