Earlier in the year I had asked my parents for a tracing of their hands (for a project for me), so I took those tracing and also took tracings of my house-holds hands.
I used a Tonal White pattern for the handprints and appliqued them to the top. Then I had everyone sign their "hand" with a Black Copic Multiliner.
I attached buttons where the lattice overlaps. A handful of years ago my Gramma gave me a large tin with LOTS of buttons in it :) Some were from her and some were from my Great-Gramma... clearly 3 buttons from this tin were just the perfect touch to finish this off.
