However, it always looks better to remove seams, when possible.  The squares turned on point can be made from the Diamond in a Square Quilt Block. 

Follow the link above for instructions on how to make this block.  There is a chart at the bottom of the page to help you determine the size to cut the squares.

This is a great sampler block, but also looks good on its own.  You can unify the block by cutting the center square from the same fabric, or you can made the quilt very scrappy. 

Here is a visual of this block with a couple other 5-patch quilt blocks.  Notice how well the 5-patches work together.  That is why the grids and patches are so important.
