Now my feet won't touch the ground
So far we've planted out lettuces, peas and radish. But Brad has been planning ahead and we have loads of tomatoes and herbs sprouting indoors.
Wooden swing base
Brad created the base out of a piece of 1"x 6" cedar. Then he added the little bottom runners to add some style (we saw them in other designs, but we don't think that they serve a purpose). To water seal the swing, we painted it with 3 layers of outdoor varnish.
Hanging from a tree branch
When choosing a rope, it is important to consider the fact that it will be exposed to the elements, so it's a good idea to get something with UV protection. Naturally it's also important to choose a good strong tree branch from which to hang your swing. It's equally important to tie the swing to the branch in a manner that won't choke off the growth of the branch. We did this by using a sliding knot.
1. We tied a bowline knot on one end of the rope.
2. We then looped the rope around the tree and threaded the unknotted end through the eyelet of the bowline to form a running bowline.
3. We then repeated the process with a second rope so that the swing would be hung between the two ropes.
A good animation of the running bowline can be viewed here.
Attaching the swing base
As former climbers, the figure 8 climbing knot seemed like a logical choice for attaching the swing base. It is a static knot that would allow us to easily make adjustments as we worked at getting the swing to be level. To ensure that the swing would be stable enough for our three year old, we went with a total of four anchor points.
1. We tied a figure 8 on the line that came down from the tree branch.
2. We tied a simple overhand knot as it went into the base.
3. We then tied a corresponding knot as the rope came back up through the base.
4. Then we finished the attachment by following back through the figure 8 knot.

Now all that is needed is a sunny day and a three year old boy!
And for anyone still wondering whether we've received our shipment from Ireland... we haven't. But it did arrive in Vancouver today! Now it's only one ferry ride away! Given the current rate of travel, I expect to be unpacking my running shoes sometime in May. My friend, Steffi, used the same shipping company on her recent move to Australia. You can find out what she thinks about the quality of service here!
