## Abstract

The present disclosure describes a procedure for wrapping an item to be sterilized with two fabric sheets in such a way as to allow a rapid unwrapping of the item for use. This procedure saves time in unwrapping and reduces the risk of loss of sterility of the item and stress on medical personnel.

## Claims

### Claim 1

A procedure of packaging an item comprising the steps of:
a) laying out two sheets, aligned, with an inner sheet on top of an outer sheet, unfolded and flat, the sheets having north, south, east and west corners with the lower surface of the outer sheet on a flat surface,
b) placing the item on the inner sheet in approximately the center,
c) folding the north corner of the inner sheet over the item,
d) folding the south corner of the inner sheet over the item,
e) gathering the southernmost portions of the inner sheet on east and west sides and folding them towards the north so that they form a “wing”, and folding the “wings” under the item so that they are under the item to form a package,
f) folding the south corner of the outer sheet over the item, and then folding the south corners of both sheets back towards the south,
g) folding the north corner of the outer sheet over the item,
h) gathering the north corner of the outer sheet with the south corners to create a six ply pleat that spans completely across the upper surface and sides of the item and laying the pleat down onto the item in the south direction,
i) gathering the southernmost portions of the outer sheet on the east and west sides and folding them towards the north so that they form a “wing”, and folding the “wings” under the unfolded portion of the lower sheet, and
j) securing the east and west sides to the outer surface of the package that is generally opposite the folded north and south corners.

### Claim 2 (depends on 1)
