## Abstract

An interchangeable drum slip that may be quickly installed to change the appearance of a drum and to provide protection to the drum shell. The drum slip is a rectangular piece of material that is pre-cut to precisely fit specific models of drums. Openings are cut into the material that correspond with hardware that is attached to the drum shell. A user installs the drum slip by placing the drum slip around the drum shell and securing the ends of the drum slip together. The openings in the drum slip fit over and around any hardware that is attached to the drum shell and any apertures formed in the drum shell. The ends of the drum slip are pulled together and secured with an adhesive. For some drums, the drum slip may be installed without disassembling any parts of the drum. For other drums, one or more drum heads and retaining hoops must be removed to install the drum slip. The drum slip may be transparent, and the drum slip may be made in any color and messages, designs, or information may be printed on or molded into the drum slip. Anyone can quickly and easily change drum slips to change the appearance of a drum.

## Claims

### Claim 1

A method for changing the appearance of a drum shell comprising the steps of:
removing one or more drum heads and one or more retaining hoops;
applying a piece of flexible material having pre-cut openings and having two or more ends onto the drum shell surface allowing any circumferentially spaced hardware attached to the drum shell to protrude through said pre-cut openings in the flexible material; and;
attaching one end of the flexible material to another end of the flexible material, so the material is tightly secured to the drum shell; and
reattaching the one or more drum heads and the one or more retaining hoops.

### Claim 2 (depends on 1)

The method of claim 1, where the step of attaching one end of the flexible material to another end of the flexible material is accomplished by use of a hook and loop fastener.

### Claim 3 (depends on 1)

The method of claim 1, where the step of attaching one end of the flexible material another end of the flexible material is accomplished by use of an adhesive.

### Claim 4 (depends on 1)

The method of claim 1, where the step of attaching one end of the flexible material to another end of the flexible material is accomplished by inserting one or more tabs cut into one end of the material that into corresponding slots cut into another end of the material.

### Claim 5

A method for changing the appearance of a drum shell having a interior surface and a exterior surface, comprising the steps of:
removing fasteners and hardware attached to the interior of a drum shell;
inserting a piece of flexible material having two or more ends around the interior of the drum shell, where the flexible material is pre-cut to fit around apertures in the drum shell and around hardware attached to the drum shell;
attaching one end of the flexible material to another end of the flexible material, so the material is tightly wrapped around the drum shell; and reattaching the fasteners and hardware.

### Claim 6 (depends on 5)

The method of claim 5, where the step of attaching one end of the flexible material to another end of the flexible material is accomplished by use of a hook and loop fastener.

### Claim 7 (depends on 5)

The method of claim 5, where the step of attaching one end of the flexible material to another end of the flexible material is accomplished by use of an adhesive.

### Claim 8 (depends on 5)

The method of claim 5, where the step of attaching one end of the flexible material to another end of the flexible material is accomplished by inserting one or more tabs cut into one end of the material into corresponding slots cut into another end of the material.
