Previously I have been using masking tape and painting tape for my roads and rivers respectively . . . which worked but wasn't very appealing
So earlier this year I purchased some of Eric Hotz's "River System" sections for my rivers . . . and I'm quite happy with them. But he hasn't got any roads into production yet; and I was tired of waiting.
Therefor a couple of days before I was scheduled to start my chemotherapy I went to our local fabric store which was having a sale and got a chunk of dirt-colored vinyl (I would have preferred felt for its "stickiness" with my table cloth but they didn't have any good colors for it).
True, I have yet to cut any road shapes out of it yet . . . I don't have a lot of energy . . . but it should work okay. I also have to decide just how wide I want to make my roads. I'm thinking of perhaps something in the 55 mm to 60 mm range because I'd like a bit of road to show on either side of my bases (47 mm cavalry & 40 mm infantry) so that it is obvious that they are on the road . . . but not too much more than that.
So I will soon have some better-looking terrain than in the past.
