The ornamental design for a quilttrimmertemplate, as shown and described.
FIG. 1 is a top view of my quilt trimmer template design showing my instructive lettering and numbers in the English language, but that language is for illustrative purposes only, and may take other language forms. The solid and dashed lines of my trimmer design are useful for trimming and cutting quilt fabric pieces;
FIG. 2 is a right side view of my quilt trimmer template design, with the left and rear side views being the same; and,
FIG. 3 is a bottom view of my quilt trimmer template design showing the English language numbers and lettering in reverse when viewed through the clear acrylic from the bottom. Otherwise the bottom is a plain flat surface.
