Shader Sprite Defuse Thickness

I've never tackled anything to do with shaders before, like this, only done the basic stuff.

What I'm trying to achieve is draw lines using a Mesh and make them look like Vector graphics from the 80s and 90s this was done with a vector screen but I'm sure unity can draw a few lines.

for example, code I created, I'm using the following

Code (CSharp):

1. public class TestComponent : MonoBehaviour
2. {
3.     void Start()
4.     {
5.      MeshFilter mFilter =  this.GetComponent<MeshFilter>();
6.      Vector3[] verts = new Vector3[] { new Vector3(-2F, 0, -7F)  , new Vector3(-2F, 0, 7F), new Vector3(2F, 0, 7F), new Vector3(2F, 0, -7F) };
7.   int[] indicesForLineStrip = new int[] { 0, 1, 2, 3, 0 };
8.  
9.   Mesh mesh = new Mesh();
10.   mesh.vertices = verts;
11.   mesh.SetIndices(indicesForLineStrip, MeshTopology.LineStrip, 0);
12.   mesh.RecalculateBounds();
13.  
14.   mFilter.mesh = mesh;
15. }
16. }
17.  

this does create the line exactly how I wanted them, but I'm not too sure how I can add a thickness to the shader so I can make the line a bit thicker when needed "Selected segment for example"

I did try to use a line renderer and yes it does work but the amount of line renders I would need is quite a few and I think this is a better way as it's much cleaner visually as well code wise.

any help on creating the shader would be appreciated.
