The sandwich fold

The medium wrap is the right size for one sandwich. The fold is the same as wrapping a small present.

Steps

Set the sandwich in the middle, diagonal to the edges. Bring the bottom corner up over it. Fold in the two side corners. Roll the sandwich forward once and tuck the last corner under. Hold it in your hands for a few seconds so the wax warms and sticks to itself.

Afterwards

Shake out the crumbs, rinse in cool water with a drop of mild dish soap, and hang it over the tap to dry.
