I am glad that, so far, in life, I have not had to join the ranks of those umpty-many folks who, at one point or another, have suddenly found themselves needing to fill a whole lot of sandbags in a hurry. Hopefully, I will never be in that situation, but when and if I am, I’m going to try to remember this tutorial by Instructables user RiverOakRanch. The jig they describe allows one person to fill six tubes at once, helps to insure equal filling, and, most importantly, frees up another laborer who would otherwise have to stand there holding the bags open.
