Seams.  The holy grail of case making is to make a seamless case.  Well that's impossible with currently technology available to cue case makers.   I am constantly playing with ways to close the seam and here are several solutions.

Riveting is the easiest, followed by lacing.  Straight lacing is fairly easy, cross-lacing is harder and lace braiding is harder still.

The hardest seam type is the closed-loop blind seam.  This type of seam can only be sewn by hand or with a very special uncommon sewing machine. The machine can only do straight lines.  We don't own that machine so all of of our blind seam work is by hand.  This is meticulous and hard work.  The result is worth it .
