Repeat Pattern Workshop

Set up photoshop document 

custom

5cm x 5cm

turn rulers on (cntrl + R)

pull guides from the rulers to each edge of the canvas

allow us to change the canvas size but still know the original size

change canvas size by percentage to 200%

lick guides in the view menu

make pattern

select central square

go to edit and define pattern

open pattern in new document

go to edit- fill then select the pattern

make the pattern on a transparent layer then you can add a colour layer underneath

add solid colour layer as a way to make adjusting colour easier.

use hue and saturation layer and make sure it only effects the layer below it by clipping it to it using the icon at the bottom of the window. 

Next Step Overlapping

move picture so it overlaps the boundaries we set at the beginning 

select the entire outer section all the way up to the boundary

chose selection tool and shift and drag the overlapping image to the bottom of the original square

then make pattern as we did with the previous image

 to do the same but working around the corner of the square more the sections in parts, each quadrant at a time using the guide lines
be careful when scaling that the image is of the correct size and does not become pixelated
you can add pattern layers using the adjustment layer tab and the bottom of the layer panel
this adds extra layers to the pattern that can be scaled
