This is a widget similar to a dohickie my grandfather used to use for holding painters fabric while he was working. as kids we would use them to make bedsheet forts and i have used them since for tarpalins when a grommit is not in a convienient place. put disk on one side of the fabric, push through hole on clip, flatten perpendicular to clip, pull tight. As I am rather inexperienced with digital design I would appreciate, if you do happen to print this, letting me know if it needs improved upon.sorry about that I uploaded the wrong file. Thank you for pointing that out. --
