Start with a cutout recipe
A dough designed to spread into soft drop cookies will not automatically become a neat cutout after chilling. Choose a recipe intended for rolling, and measure flour with the method it specifies. Adding handfuls of extra flour to a soft dough can make the final cookies dry without solving the underlying balance.
Cool dough, cool trays
Divide the dough so only a manageable piece is out of the refrigerator. If shapes soften while you transfer them, chill the filled tray until firm. Never put fresh shapes on a hot baking sheet: their edges start melting before the oven has a chance to set them. Rotate between sheets and let each cool fully.
Keep thickness consistent
Roll from the center outward and check more than the outer edge. A thick center with thin arms makes uneven baking almost inevitable. Dip cutters lightly in flour and tap away excess. Lift shapes with a thin spatula, or roll on parchment and remove the surrounding scraps rather than lifting a delicate shape.
Bake shapes of similar size together
Small stars may finish before large people, even at the same thickness. Separate noticeably different sizes onto different trays. Gather scraps gently and limit rerolling because each pass adds handling and sometimes more flour. Let baked cookies settle on the sheet before moving them; fragile warm limbs firm as they cool.
