How to make leaf mould

Leaf mould is a kind a nice, rich kind of compost that you make from leaves. I went and gathered my leaves in a neighbouring street, as my garden only has one tiny tree and there aren't any trees down our road. The neighbouring road in question is a nice quiet one. This is good for two reasons: 1. fewer people pass by to give you strange looks for gathering up leaves from the pavement and street and 2. the trees haven't spent all year being polluted by vehicle fumes (conventional wisdom is that this is a bad thing for the compost you make).
So, here are the instructions:

1. Gather some leaves in a plastic bag the size of a bin liner.

I found the most efficient way of doing it was to sweep the leaves together with a garden broom, then use a dustpan and brush to grab them and deposit into the bag - more like using tongs or chopsticks than like using a dustpan and brush.
The BBC says: Oak, alder and hornbeam will soon rot down, while sycamore, beech, horse chestnut and sweet chestnut take a little longer. Leaves from conifers and evergreen plants will take between two and three years to compost and are best added in small quantities only, shredding them first to help speed up composting.
I don't have the faintest idea what sort of leaves I've gathered. Some small, red thick ones at the top of the bag and some large yellow, thin ones underneath. Given that the yellow ones had already started to rot in the road, I think the rough rule of thumb is the thicker the leaf, the longer it takes to rot.

2. Poke some holes in the bag.

My bag came with holes already in it, as it was previously the bag the council gathered garden waste in before they switched their system and they never survive more than two collections without the addition of a few tears.

3. Sprinkle on some water - not too much, you don't want them to go slimy (in fact that's what the holes in the bag are for, to let water out and stop them getting all slimy).

4. Tie up the top of the bag and leave somewhere shady and not too conspicuous for 1-3 years (1 year = low quality leaf mould, 2 years = high quality leaf mould providing you've used easy-rot leaves, 3 years = high quality leaf mould even if you used stubborn leaves.

I'm leaving mine behind the shed, at least until we get a new shed. Then I'm going to have to think of a new home for it.
