Victorian Tiling tips?

[Oliver T]

Subfloor reinforced, cement boards stuck and screwed and taped down. I’ve drawn the pattern and Practice laid the border and pattern tiles. My Question is . Should I tile down the border or the inner pattern first when tiling ? Just wondering which is best and if there is a reason to doing one first Thanks in advance

Do the border first then you can center the inside to that
