Photocall (or other) clamp with fixing

Tired of having to unroll the paper every time I do a photo session, and all the hassle that entails, I decided to create some supports that would make the job much easier. For this I have created these clamps to which DOUBLE-SIDED TAPE must be ADDED to stick wherever necessary (in my case the bottom of a shelf), once you have put the clamps you need to hold the fabric or paper (depending on how big you want to make the photo background), simply fix the clamps in the “open” position, and calmly place the photocall background, while easily closing them with the tab designed for it (if it does not close automatically).
