Looks nice.......you did a great job!
We planted a lot of plants and shrubs right up to the liner that eventually grew and draped over the "necklace" of rocks, breaking it up. In some areas we did like Annette said and tucked plants among those rocks like water celery, water forget-me-nots, mint, etc. You will be amazed at how quickly things fill in and you don't notice the liner.
to the forum, I'm down south.........near Terre Haute.
