Seashell-Villa Rosa, started as a way to float 5" Charm Squares in a background.  To accomplish that I thought setting the squares at the end of a 5"x 9 1/2" slice would do the trick.  I didn't want the same background with all of those seams, so I chose to make it with 2 different, but similar, background fabrics.  A strong contrast in the backgrounds would create a stripe effect, which, in the right combination of fabrics might work.
Then I am thinking, that this pattern is really a Bricks and Blocks.  Usually that pattern is done in 2 1/2" or 3 1/2" wide Bricks, but why not our big 5"?  We love to show off our pretty, larger prints.  A little pack of 10 Fat Sixths--our Sheet Cakes (12"x 22")--will cut perfectly into 40  5"x10" pieces.  A single light background will work for the squares, though I used a Tonga Creamsicle pack.
