Step 11 Now you have a complete shape, it’s time to start creating the repeating pattern.

First, create a new Illustrator A4 document, and place your finished crest in the centre. When making patterns, make sure to use the Align tools to get perfect alignment – never by eye.

Make a copy of your crest, and align it in the centre of the left-hand-side edge of the canvas, then again to the top edge. Make another copy and align it to the bottom edge, making sure you use Smart Guides to ensure perfect placement.

Once you’re happy with the result, do the same on the right-hand edge of the canvas. You should now have a rough pattern that will repeat to infinity.

You can quickly test this by drawing a rectangle the same size as the canvas, and masking your pattern with it. To do this, select everything, then hit Cmd/Ctrl + 7. Drag a copy to each repeating side to check it tiles correctly. If not, make the necessary adjustments – a nudge or two – and test again.

Step 12 Once you’re happy with the way your pattern is tiling, you can build up a colour scheme for it. I’ve chosen a monochromatic palette of blue and green shades to give the finished pattern a subtle, classy finish.

Step 13 At this point, the pattern is looking a little bare, so I’ve decided to add in some extra details in the form of pinstripes and a wave pattern that surrounds the crest. Again, the principles of making a tile mean you need to ensure that whatever leaves the left-hand pasteboard, will match up on the right-hand side. This is very easy when dealing with straight vertical or horizontal lines, but more difficult when using angles, so practice with something like this first.
