A quilting tool for use with commercial quilting machines with a base, a pair of handles and a narrow strip of the hook portion of hook and loop type fastener. The base is planar and rectilinear and has a plurality of spaced apart grooves that are defined on the bottom surface. The first grooves on each long edge of the base are spaced one quarter of an inch from the long edge. The second grooves from each edge are spaced one half of an inch from the first grooves. The two medial grooves are spaced apart one inch. The handles are dowel-like and extend upwardly from the top of the base and are spaced apart from each other by approximately two and three quarter inches. The hook strip portion adhesively attached between the grooves on the underside of the base and aligned to be directly under the handles.

Quilting tool

A pontoon comprising a seamless, non-woven, one-piece, inflatable vessel preferably formed by a process of rotational molding, from a resilient, semi-rigid polyolefin elastomer, preferably metalocene. The pontoon has shape memory characteristics, which make it partially self-inflating, and cause it to entrap air when partially deflated, to thereby resist complete deflation if punctured, allowing a user to more easily get to safety. Punctures in the pontoon may be easily eliminated by applying heat to the polymer material at the site of the puncture, such as with a hot knife or other metal implement, so as to fuse the polymer material together. The bottom of the pontoon is preferably thicker than the top, and the ends of the pontoon taper to a blunt point that is thicker still, to thereby resist damage from impact and to help maintain the desirable shape-memory characteristics of the pontoon. The pontoon is tolerant of significant relative pressure changes without substantial deformation or change in its shape.
