Abstract: A sheet of flexible material such as fabric or plastic is provided with flaps, loops and ties so that it can be laid over a pile of loose material with rigid sticks attached to loops along two parallel edges of the sheet and the rigid sticks can be grasped by the user and forced together between the surface and the material forming an open ended envelope containing the material which is then turned over and the flaps at the end of the envelope pulled up and tied over the ends to close the envelope while the two sides made rigid by the sticks are tied together. Then the sticks may be removed leaving the flexible sheet formed into an envelope that encloses the material and so forming a bag containing the material for disposal.
