This shows how small this pattern can go to be set as a border. Using tesserae which are 10mm (7/16″) will give you a 24cm x 24cm (9 1/2″ x 9 1/2″) square to put a centre piece in.1. Mark a centre point and draw in horizontal, vertical and diagonal lines.
Mark line A on the horizontal to the measurement shown. This will sit between the diagonal lines. Do the same all the way round to create the square.
B is the outer line, 14cm out from A.
2. Mark the first of the single white centre tesserae, D on the diagonal lines. This will be 7cm (2 1/4″) from the side.
mark the other centre tesserae along the mid line and these will be 9.5cm (3 6/8″) apart which will give you, including the corner ones, 5 centre tesserae.
3. And that’s it, just draw in the pattern, refer to 4 if you need to. Note, this drawing isn’t to scale but drawing 4 is.
This is the minimum size that you can set with this border, you can make it slightly smaller by using just 2 lines of colour tesserae instead of 3, in which case you need to reduce the mesurements accordingly.
