When fly fishing, you often need to dry a fly that has become saturated. This is a cheap and easy way to do that. OR, but a few keys on the cork and ensure that they don't sink if you drop them in the water.
A length of paracord and a wine cork is all we need.
12-18 inches of paracord
Corks (synthetic or actual cork)
Drill with bits
Scissors and lighter
Step 1: Drill the Cork
Use a 1/4 in bit for synthetic corks (pictured on the right) and a 3/16 bit for a real cork.
Drill in the center of the cork, all the way through.
Use a screwdriver to help clean out the hole once drilled.
If you don't have a drill, you can use a screwdriver to press a hole into a real cork.
Step 2: Tie a Lanyard
I use a diamond or lanyard knot.
Push the center of the cord into the cork and push through. (See photo with black cord and the following.)
Then tie the diamond knot. - In one end form a loop (photo 4). Pass the other end under and around the loop (photo 5). Pass this end around outside the bight and up through the center (photos 6-7). Do the same with the other end (photos 8-9). I used a screwdriver to show the path the end will take. Tighten both ends to form the knot and then snip the remaining cord and melt the ends.
Step 3: Use Your Imagination
Different numbers of corks, arrangements, and knots can be used to make a variety of items. If you are using the cork for a floating keychain, be sure to test it in the sink or a bowl to make sure there is enough buoyancy for the amount of keys.
