Patent ID: 8677546

Claim:
A method comprising: inserting a first end of a first linearly constructed material along the length of a first opening of a sponge in a first direction and then inserting the first end of the first linearly constructed material along the length of a second opening of the sponge in an opposite, second direction thereby forming a first loop at a first end of the sponge; inserting a first end of a second linearly constructed material along the length of a third opening of a sponge in the second direction and then inserting the first end of the second linearly constructed material along the length of a fourth opening of the sponge in the opposite, first direction thereby forming a second loop at a second end of the sponge; forming a first knot using the ends of the first linearly constructed material; forming a second knot using the ends of the second linearly constructed material; inserting the first linearly constructed material in the second loop; and inserting the second linearly constructed material in the first loop.
