Well Ali, here's a picture taken today. The two beds in the background are finished. The one in the foreground shows the starting point- dug out ready to lay the foundations. As the experts always say, once you have got a level base the rest is easy(!)(?)
(The bed to the right is just a mock up from last year to check what it would look like and whether I had enough bricks).
In between these two stages is this stage: laying the foundations. You need sand/grit/cement to bed in the bricks sideways on so that it is double the width of the wall. If you don't have lots of bricks the usual advice is to fill the trough with concrete. (In our case all the materials for the garden have to go through the house so we don't favour bulk materials like hardcore and concrete)
And of course you need the raw materials:
They need cleaning up before they are ready to be used.
There are quite a few steps and you have to allow time for each step. One correspondent suggested that when it comes to bricklaying you should just do four at a time (thanks Iggy). I thought he was joking, and with 400 bricks to lay I was more adventurous. It turned out to be good avice. The main point is not to rush it. Bricks are quite heavy really and a bricklaying session is like a weightlifting session - not to mention mixing the mortar. And as for circular beds - that's beyond my expertise
The foundations should be twice the width of the wall
Start the foundations from the LOWEST level.
Use a spirit level at every stage
The advice is that if you use a single width of brick (a halfbrick wall) the maximum height is 18 inches
So on a scale of 1:10 I would say 7, but if it is only 3 bricks high (like me) 4.
