The goal is not perfection but preparation. As in, be prepared to make mistakes, most of which you won’t notice in the final result, the rest lending the project more character. If you make a mistake that feels essential to fix, simply wipe the area with a clean cloth and start over. And if this is your first foray, it’s a good idea to gain confidence by painting an out-of-the-way bedroom or an upstairs hall before tackling a more prominent area.
To create a gingham floor like the one pictured above, start by measuring the dimensions of the floor and making a scale drawing of the pattern. Measure the room carefully, and disregard the width of the floorboards, so the pattern is even.
Dirt and grit act like sandpaper on painted floors, so the key is to vacuum the surface regularly (and enact a no-shoes policy). Clean up any spills as soon as possible. Clean dirty spots with a damp cloth or mop wrung out in a mild household cleaner. If the floors are scuffed, use your go-to spray cleaner or, if necessary, a gentle abrasive, making sure to dry the floors immediately.
