I have a Kifaru Sawtooth shelter and often use it floorless. However, I would like to have a backup floor for wet conditions. Has anyone ever worked with 1.9 oz ripstop nylon for a shelter floor? Since I have only found 60" wide material, I would need to either sew or glue two widths together to get it wide enough. Anyone done this or have any other recommendations for a floor? Thanks.
