Looks like you have a nice focus fabric ... careful you don't chop it up so small you lose the beauty!
I had already been thinking of an assortment of plant/flower fabrics put together. There's lots that are garden like and not ultra-feminine.
One that I like to see is a focus fabric with log cabins around it to frame it up. And additional log cabins added to make a combo pattern. There was a beautiful one posted not so long ago by one of our posters!
Or, you could use the trellis effect around any focus fabric that I did with this quilt. Right colours, still would be quite he-man!!!
