Archery tip of the day

[Tartar Horde]

Carpet hung loose BEHIND a target can make an effective backstop, but for more powerful Bows I would suggest using a few layers. If you can get a gap/space between the layers it will be more effective at stopping arrows.
Targets for Archery can be expensive but there are many alternatives to spending good money on something to shoot holes in.
Cardboard boxes normally come flat packed and can be had anywhere, simply get 10 of the correct dimensions for an archery target and Gaffa tape them together. Depending on the poundage of your Bow you might have to add more.
Flat screen TV boxes etc are another great source, simply stuff with rags/old clothes to the density enough to stop Arrows.
Pillows are really good at stopping Arrows due to the nature of the material inside, but again adjust for the power of your Bow.
Straw Hay bales are very good at stopping arrows but surprisingly I won't recommend using them as eventually they will fall apart and you end up with Hay all over the place, unless you can use it of course. You might have difficulty getting such a Hay Bale in a Car as well.
