I designed this sign in fusion 360. You weave the wire in and out of the sign. It is pretty straight forward because there is a path for every color. Some spots may be hard to bend it but I was able to get them all in. You have to weave one of the strands under the letters so that part can be a little tricky to pull out. I just drilled a hole in the back to mount it.
The ones I used are on amazon. Make sure to get the .09 inch ones(2.3mm).
I used an ice blue, red, and white strip.
