Sheet Bend
The Sheet Bend (or Weaver's knot) is good to use when you want to join a thick line to a thin one, or attach a rope to a loop or ring. They use this knot on steamboats when the big hawser can't be thrown on shore, but a light line can be attached and easily thrown to the dock. It is a good knot for Scouts to use when making a guard line to keep back crowds, at a rally for instance. With this knot you can join your wool when knitting, and it is an excellent way to attach a fly to a fishing line.
Make a loop AB with one rope; pass the end, C, of your other rope through this loop, round both sides of the loop and down under its own standing part. Pull firmly.
Clove Hitch (or Builder's Knot)
The clove hitch is used when fastening two poles together as in scaffolding, as either end will stand a strain without slipping either lengthwise or downwards. It is also used to tie a boat to a stake, or in First Aid to tie on a split.
Pass the end around the post, below the standing part; around the post again, over the standing part, and tuck it down between the standing part and the turn.
