Step 4: Continue Gluing Tiles
Continue gluing tiles in circular rows based on your central row of tiles.
In order to make the rows fit neatly, my technique was to lay down half a row or so, and then carefully hover another row of tiles around the other side for length, cut to size, and place. If when measuring the second strip there is a significant gap (you can't quite fit that extra square), stretch the tiles as much as possible when placing the second strip to distribute the space evenly. This is one of the advantages of having tiles backed in fabric, as it was relatively easy to make the rows fit without any large gaps.
