The call of the wild came this afternoon and taking a keyboard which had the keys removed and which had been partially painted silver, I removed the plastic inserts using what tools I had available. The wire cutters were not optimal but they worked.
The third photo shows how changing hue and saturation can affect the result.
And finally, the bottom shot shows the blue beads which have actually been pounded into each not-so-round hole. A bit of glue was added before the pounding began.
I know what this is starting out to be but uncertain if it will become what I mean it to so won't blow my cover just yet.
