I like the bargello pattern she picked. It looks like that one is worked in quads then the 4 sections are pieced together. That would be my guess anyway :)
I would be tempted to make the two hearts in a single color range with single contrasting outer border monotone range. The pattern as printed has 3 color ranges for the hearts.
but ... as you can see from my avatar .. I love using monotones for bargello :)
