How can I clean up the look of my old blinds?

I have ancient discolored metal horizontal blinds in my classroom. I’d like to cover them, at least partially, with a valance, and then let my posters cover the rest. I’m looking to soften the institutional look going on. Any ideas? Help!!

    You've done such an amazing job adding all those beautiful quotes. This article might help. The lady sprayed her blinds and created a valance too. https://designeddecor.com/lessons-learned-spray-painted-blinds/

    Wash the blinds outside over a fence. For the top use a pink insulated board from Home Depot (foam board), measure and cut, use cut dowels to glue into the front and both sides to hold everything together, then place 2 L brackets and sit your top on it. Cover each piece with fabric or color paper, before dowels, glue.
