Piano Key Border for my Mystery Quilt

I'm caught up with the clues for the Mystery Quilt by Heather Spence (Jack of Hearts).  Of course I want to make this quilt bigger (like always) and made my first piano key border today.  Thanks again, to my Accuquilt GO! Baby 2.5" strip cutter.  Pieces were cut with accuracy and quickly went together.  I should be the spokesperson for Accuquilt, but I'm not. This is just my opinion through experience using it.  Love ya, Baby!
