While organizing my metals recently, I rediscovered some textured pieces that had been ignored for too long.  
A piece of brass that had been etched was paired with a piece of copper 
that I had milled with a loosely woven fabric.  Both pieces were filed 
and sanded before being soldered together. 
I liked the simplicity of the metals and dismissed the idea of drilling into the copper to provide for connecting to a chain. 
I instead chose to cut a segment of brass tubing for my bail.
Both ends were filed and sanded before soldering the tube to the back of the copper.
I had also filed the length of the tube to create a flat plane, ensuring that the tube would sit nicely in place while I did my soldering.
Aaaaackkk!  
Wouldn't you know.....things somehow went a little wonky while the solder flowed, and the left side of the tube shifted ever so slightly downward. 
I haven't put this on its chain yet to determine if it sits crooked, but I may have to heat this again to nudge the bail into proper placement.
And so yet again, soldering reminds me that I am rarely in control.
