My DH built a lattice wall for me but it was very heavy and required two people to set up. I would think plastic would make it much lighter (mine was wood) He used 2 x 4 and hinges and then made removable stands for it to sit in. It was very cumbersome but did an excellent job. I used S hooks to hang from the lattice and that little drying rack thingy, not sure where I picked it up, but I pounded nails in it to hang the art work from.
Lattice is in the back with quilts hanging on it
