Quilter7x,
If you want to have less of the backgroung and more shamrocks I think that it would look great with more shamrocks...you could easly turn that 3rd row into a full row of shamrocks...I didn't even think of that but I think that it would look great.....but I think that I would still space them out a bit - wiht a little division - like the hearts..otherwise I'm afraid it may look too "crowded".....
Once we are doing the blocks we can easily make our own twist on things...
