We started off by taking a piece of aluminium and drawing 2 straight lines on it. I decided on 1 line going vertically and then another going diagonally.
We were then told to cut it you had to use a big guilitine, you had to line it up accurately by looking through the gap and then standing on the bar to cut through it.
Then we put a pattern on one of the pieces and used the gritting machine to grit the side of the aluminium strip and when the masking tape it peeled off it has a permenant pattern on it of shiny/matte.
These are my final metal pieces:
