Once you have it cut to the right size we need to make some cuts in the strips to make the circuit, flip the board over onto it's 'metal strip side' and using either a tool like this one or something similar or a 3.5mm drill bit make shallow holes just enough to break the metal strip at that place... you don't need to drill right through the board... the places you need to do this are marked in red below.

When you flip the board back to the plain side the cuts you make will be underneath in the places shown in red (if you imagine the board is transparent)

Almost all layouts you'll find online are like this, and it can be a little confusing at first as when you flip the board over to make the cuts it will be in a reverse position from where it looks on the layout ... what I used to do when I first started was poke a resistor leg through the hole where I needed to make the cut then flip the board over with the leg in place so could see where I needed to make the cut. It's something you get used to though and now on a simple build with not many cuts I can visualize and flip the places in my head. another method I use with more complicated builds is to do a sideways mirror flip of the layout in a photo editing program, then the strip cuts will be shown as they would be on the metal strip side.
so to recap, the top picture is what your board should look like from the metal side and the bottom pic is what it will look like from the top (plain) side.
OK? any questions? :)
