The ornamental design for a frontface of a window covering, as shown and described.
FIG. 1 is a front elevational view of a front face of a window covering showing my new design, the front face of a window covering being shown in an open, pulled-up position.
FIG. 2 is a side elevational view of the front face of a window covering of FIG. 1.
FIG. 3 is a front elevational view of the front face of a window covering of FIG. 1, shown in a partially closed position.
FIG. 4 is a side elevational view of the front face of a window covering as shown in FIG. 3.
FIG. 5 is a front elevational view of the front face of a window covering of FIG. 1, shown in a fully closed, pulled-down position; and,
FIG. 6 is a side elevational view of the front face of a window covering as shown in FIG. 5.
The broken line showing of a back face of a window covering in FIGS. 1–6 is environmental only and forms no part of the claimed design. It is to be understood that the design pattern shown in the front elevational and plan views continues throughout the length and width of the front face of the window covering. The front face of the window covering is shown broken-away both vertically and horizontally in the front elevational views and broken-away vertically in the side elevational views to indicate that a specific length and width forms no part of the claimed design; and the single panel of the front face of the window covering is shown broken away horizontally to indicate that a specific width forms no part of the claimed design.
