Abstract
A device for detachably adhering a manipulative to a substrate using electrostatic charges is described. The invention comprises a thermoplastic substrate having imparted thereto a substantially persistent electrostatic charge with paper and/or fabric manipulatives removably adhered thereto by electrostatic attraction. The present invention may be useful for creating visual displays such as display boards, design boards for quilting patterns, sewing patterns, and toys such as dolls and educational games or aides using manipulatives in visual displays. The substrate is preferably made of polyolefin nonwoven webs, particularly polypropylene or polyethylene meltblown webs.
