The wire is 22 gauge. The copper bracelet is thin. Adding some beads will easily make a change.
This kind of wire weaving is better looking if kept looser.
About the length needed, I did not write it down this time and how come I can't recall it now.
I think the pattern is very clear. As you can see in the photo, it's not flat, it has some 3D style as its feature. It's different from normal braiding. The normal wire braiding will be flatter than this.
