Ingredients and tools:
- Heavy duty tarpaulin, 1.2 x 1.8m should be enough
- Scissors, chalk, a sewing machine and some strong thread
- Old clothes, a bucket of sand (20kg) and some freezer storage bags + a scale (optional)
- 1m of rope, a hanger and a carabiner (you can substitute for something else)
Time and cost:
tarpaulin – 3 pounds, rope and hanger – 2 pounds, carabiner – 5 pounds. 10 pounds in total, not counting sand and clothes, which you should have lying around. Time used (in my case) was a couple of hours.
- Get some heavy-duty tarpaulin, for example here. This will set you back 3 pounds. I had one lying around, so I used that. You want it to be reasonably strong and preferably with some brass eyelets.
- The tarpaulin then needs cutting. Use a chalk to outline the cut and go for it. Small mistakes here don’t cost much, so you don’t have to be super precise. A rule of thumb can be to cut out a square piece or something similar. This will keep ratio of the width and the girth of the bag nice. In my case, I cut 1.2m (length) x 1.1m (circumference). Mind where you have your eyelets (should be on the top).From the circumference, determine the radius of the piece for the base by dividing with 2pi (6.28). In this case, that would be 1.1m/6.28 = 17.5cm.Outline and cut. You should now have two pieces which can be sewn together.
- You can sew by hand or with a machine if you have one (much faster and better). This can take some time, so be patient. After you’re done, get your bag (looks nice already :)), old clothes (smaller pieces are better) or something similar (I guess pieces of an old mattress would work as well, or some foam pieces), a bucket of sand and some storage bags. You want to fill the bag with sand and clothes. The clothes are there for softness (when punching), the sand is there for added weight. I used about 20kg of sand distributed in 14 bags.
- Start filling. Put a layer of clothes, compress the best you can (say about 10cm of clothes) and add a couple of bags of sand. Always keep the sand bags in the middle of the bag, to have them protected. Put more clothes on top, some more sand bags etc. – you get the picture. After filling for about 20 minutes, you will have a heavy, self standing bag. Mine turned in at about 45kg. Here you can see a layer of clothes with some sandbags on top.
- After the bag is done, you should put some rope in the eyelets. Measure the width of the eyelets and get a rope that is as thick as possible and that still fits in. You need some heavy-duty equipment here. I attached a carabiner to the rope to connect to the ceiling more easily. Finally, mount a hanger in your ceiling. Depending on your ceiling (wood or concrete or whatever), choose a hanger that will fit best. Attach the carabiner and voila – you’re done.
