I got around to ordering a bunch of stuff off Tiergear (thanks simonm) and spent two evenings making this tarp. It's yet to be seam sealed however I reckon it's pretty well finished.
1.5x2.8m, 250g (excluding lines and pegs), perfect for the solo trips or an awning for shade.
Total build time was around 6hrs including sewing machine jams, breakages etc.
