I claim the ornamental design of a yoga mat cover, as shown and described.
FIG. 1 is a left, front perspective view of a yoga mat cover;
FIG. 2 is a top plan view of a yoga mat cover;
FIG. 3 is a front elevational view of a yoga mat cover;
FIG. 4 is a rear elevational view of a yoga mat cover;
FIG. 5 is a bottom plan view of a yoga mat cover;
FIG. 6 is a left side elevational view of a yoga mat cover; and,
FIG. 7 is a right side elevational view of a yoga mat cover.
The broken lines and the area within the broken lines represent the unclaimed yoga mat showing the design in a position of use and the unclaimed portion of the yoga mat cover. The broken lines form no part of the claim.
The surface shading represents the surface of the yoga mat cover.
