step 1

step 1: i placed the sketch in a new file of adobe illustrator so that, i can trace the image exactly the same. i clicked the 'file button' then click 'place button'. a 'place box appeared is to select the file of the sketch that i saved. after that, i stretched the image by pulling every each small square of the edge to make it fit in the page of an A3 size paper. later, i double clicked the 'layer 1' link then, then 'layer option' box appeared. i ticked the 'template' button and dimmed the images to 20 %.
