What can you give your dad when you can't get to the shops without him, but you can get in his shed?
Two bits of paracord, a lump of technoscrap, and some Scouting know-how, and you have a gift fit for any cool dad.
Step 1: What you need.
It's really easy - two pieces of narrow paracord, left over from something else, and something small with a hole in it.
I used a ceramic thing that came out of a computer, but you could use anything that's the right size and has a hole in it. Maybe cut a piece of wood and drill it.
