Trim the joining edges
Use the corner marks as a guide. On every page after the first column, trim the left edge. On every page after the first row, trim the top edge.
03
Match the repeated image
Slide the trimmed page over its neighbor until the repeated image area lines up. The page labels show the left-to-right and top-to-bottom order.
04
Tape from the back
Use two small pieces first, check the alignment from the front, then add a longer strip along the join. Assemble rows before joining the rows together.
