After you’ve found your workspace, sorted your pieces into edges and other categories, you can start building. Begin with the puzzle’s edge pieces and build the border first. This method is useful in visualizing the scale of the puzzle and the approximate area of each section.
Then move on to one of the segregated categories and focus on locating where it belongs relative to the border. If the puzzle contains high-contrast, detailed sections, begin with those collections first. Leave the low detail/plain pieces for later, as they’re harder to place without some development for context.
