The other thing to bear in mind is that once you've put some form of edging in it obviously limits the ability to modify the borders. I've used plastic edging in the past and it's partly done the job, in that it does make removal of grass overgrowing, and weed ingress, into the borders easier. If I was going to put permanent edging in again I would bite the bullet and get good quality metal edging. It's used in parks and large gardens as it avoids the need to constantly recut the edges and prevents edge collapse with heavy footfall.
I'm glad I haven't put anything permanent in yet as, although I was sure at the time that I was happy with the line of the borders, I have since started to reconsider the lines. Yes, I could have removed metal edging and reused it but it would have been a lot of work. I do have problems with some of the grass edges collapsing but haven't been able to work out why yet. None gets any more traffic than the rest, and some is still solid.
Just the wonders of gardening I guess.
