Challenge - Grid

I made this card for a home card challenge at CST.  The challenge was grid or inchies.  I have started with a turquoise card and I added a 3.75" square of black card stock.  I added small 1" white squares to create the grid.  I added small handmade paper cards in turquoise and yellow.  The blue on the white squares held with tiny white brads.  The yellow in the black squares held in place with black brads.  I stamped the greeting in Onyx Versafine ink with a clear stamp.
