You need 1 army issue duffel bag, easy to find on ebay (£9-10).
Sand, £1.50 for 20kg, b&q, homebase etc. Best not to use sharp sand.
6 x 9 inch sandwich bags,
fill each sandwich bag with 1 kilo of sand, seal and put into another sandwich bag and seal that one (doublebag). And fill as many as you need. Took about an hour to fill 50 bags.
Put into duffel bag. That's it.
In the photo I tied string at each end so the weight was evenly distributed. I think I was doing farmers walks that day.
