The following steps show how to efficiently pack a tent and all its components.
The photos shows what we don't want. In this case the fly separate to the rest of the tent, taking up extra space and everything else stuffed into the bag. This is how it was delivered to me from a friend of mine.
Step 1: Packing up the fly
With a bit of practice and two people it is really easy to sweep the fly off the erected tent (after removing/undoing all supports) and end up with it folded lengthwise.
Step 2: Folding the fly
If this step is done correctly, the fly should be the same width as any of the folded poles, as shown in the last picture.
Step 3: Rolling up the fly
The tighter the fly is rolled the easier it will be to get it into the bag at the end.
Step 4: The main tent
Ensure all zips are done up, including the windows.
Step 5: Adjusting the roof
Make sure the front door is flat, with the excess laying over the rear door, as shown in the second photo.
If you have a dome tent without a vestibule, work in a circular direction and pull each side tight before finishing with the front.
It really helps to have the tent still pegged at this stage.
Step 6: Folding the vestibule
Make sure the front one is on top.
Step 7: Folding the tent
Step 8: Putting it all together
First completely roll in the fly
Add the poles and roll again (a half turn works here to keep it in place)
Add the pegs and roll again
Add anything else and roll up to the end and tie.
It is important to roll the tent tightly, if there is too much air once rolled it wont fit in the bag.
