From time to time we’ll post answers to reader’s questions.
Q: What methods can be used to close the ends of earthbags?
A: Most people fold the bag ends over and then butt the folded end tight against the previous bag. (This keeps the contents intact and prevents spillage.) That’s the fastest way. If money is tight or you just want to minimize the number of bags required, you can sew the bags closed with cord or 15-20 gauge galvanized wire, or pin them closed with nails. These methods use fewer bags because you can fill them more completely. This simple step can reduce the total number of bags required by about 17% when using 18″x30″ bags: folded ends 20″ long; sewn ends 24″ long.
