Always good to see how others have done same job. I spent a while getting into the American terminology, eg Windlace is the US version of Draft Excluder such as Furflex. Another point, I pinned my panels together with the bias binding (or US version - listings) before stitching and used a hem guide, a side stop or guide to keep the stitch line parallel with the edge of the hem. I found stitching rewarding, perhaps because I had spent a heck of a long time getting to that point and at last something was getting finished. Unfortunately, I didn't have a pattern to copy as neither of the cars I am doing, upright Ford Prefects, came with a headliner. One mistake was not making my own patterns for the back section and just guessing the shape needed as the back curved down and in. The second one has paper patterns to follow and this will be getting started soon.
Another lesson I learned along the way was to fit all the Furflex first. This is tacked with either 6mm or 12mm tin tacks and must be installed taught or else there will be small carbunkles as you go. Alternatively just put a temporery tack here and there to keep the Windlace out of the way as it can get under your feet before its finally fitted. If you have to lift the Furflex to re-tension, the tacks will come out with careful use of a 6" rule or one of those forked little crow bar tools. Use only enough tacks to keep it in place, more round curves but about every 150mm on the vertical straights, and use tacks no longer than necessary. For the kickboards I removed the self tappers one at a time and tucked the Furflex fixing tape behind the board and then replaced the screws, making sure the tape is well tucked in and taught. The original Ford installation had the tape sewn to the board before the board was fitted. Next, out with the steamer to try getting a few wrinkles out.
