may have edges 10 a 10 b 10 c 10 d and the deformable member may have edges 14 a 14 b 14 c 14 d the preferred distance separating edge 14 a which is a lengthwise edge from 10 a also a lengthwise edge is between 9 and 10 inches likewise a preferred distance between edges 10 c and 14 c is between 9 and 10 inches for the smaller dimensions the preferred distance from the shorter edge 10 b of the towel to the shorter edge 14 b of the deformable pocket is on the order of 4 to 5 inches likewise the preferred distance from short edge 10 d to short edge 14 d is similarly 4 to 5 inches preferably a pair of grommets 20 are affixed to the towel 10 in line with the deformable member 14 thus grommets 20 are located generally centrally along the shorter edges of the towel at the outside margin as shown in fig1 nominally the grommets are 1 inch in diameter at the outer dimension and have an opening of about 0 5 inches grommets 20 may be made of metal or can be a synthetic or even rubber variations can be made with respect to deformable member 14 it does not need to be a pocket filled with microbeads but can instead comprise a different deformable structure any substance or material that one would use in a soft bed pillow is generally suitable as a member 14 as the member 14 acts as a pillow for the mallet or other striking device an example of a substitute would be an easily compressible foam rubber pad that is preferably is covered with cloth other soft deformable.
