The Hook and Eye Dressing Frame (D 020) is a classic practical life material from the dressing frame sequence, isolating the specific hand movements required to fasten and unfasten hook-and-eye closures. It is appropriate for children in the 3–6 environment who are ready to progress beyond simpler fasteners like buttons and snaps toward more refined finger control and bilateral coordination. Having this frame as part of a complete dressing frame set ensures children encounter the full range of fasteners they will meet in daily life.
