Fundy Direct orders require a minimum of 10 spreads/20 pages. You can find page/spread requirements listed at the top of the software.
To order an album with fewer spreads, export for print and place your order through your chosen lab (such as using Miller's ROES).
For more info about exporting for print and ordering through ROES check out these tutorials:
