It's personal taste, but I find edging within 6 feet or so of the house usually looks better following the (level) lines of the building rather than the contours of the yard. Not so bad with larger beds because you can compensate by using a greater variety of different size plants. Might consider a fairly flat mowing strip rather than other taller edgings if you don't have much slab between your soil and the bottom row of bricks.

Penny, please don't apologize....it's what we're all here for ! Sorry i don't have any ideas on the edging question. I don't like edging. I prefer using rock or timbers.

Speaking of using rock for the defining edge scroll down about four photos on Pam Penick's blog Digging.

I like rocks too because they can be easily moved if you want to change the planting area. But I live in a rocky area so they are fairly easy to come by, plus I use pieces of broken concrete, affectionately known as "urbanite", hunks of which were left over when some houses on slab foundations were removed in my area.

I still have places with the readily available steel edging. It's pretty easy to install and it doesn't show when the grass grows up to the edge.
