The ornamental design for a pacifierholder, as shown and described.
FIG. 1 is a bottom plan view of a pacifier holder, showing my new design;
FIG. 2 is a right side elevational view thereof, the left side elevational
view being a mirror image; and,
FIG. 3 is a top plan view thereof.
The cross-line pattern on the surface of the design which is partially
shown for ease of illustration represents a conventional fabric. The
broken line showing on FIG. 2 represents top-stitching.
