Mow easily and stop weeds with landscape shingles

Its that time of year again!  Back to maintaining the lawn and gardens.  Actually, I enjoy mowing the lawn.  The hardest part though is mowing around the flower beds because they are outlined in rocks.

My friend had a great idea (all these photos are from her beautiful yard).  She went to Home Depot and bought a package of roof shingles.  Then she tucked them under the rocks around her beds.  She cut them to fit, as she worked around the curves.  Not only does it make for easier mowing, but it keeps the weeds from growing in between the rocks!  And, I think they look like embedded bricks!
