Is this even salvageable?

I admittedly had no plan and so little experience, but i was determined to make a patchwork tablecloth today and have failed miserably. I started the day so excited to finally have time to sew, with sort of an idea, only to spend all day just to wind up with...this. I had accepted it's wonky flaws but the teal border is just so...wavy? Ugh. Is the whole thing just garbage or can I save this somehow?! I wanted to keep adding layers but at this point I'm not sure if I would be better off just giving up. I'm so disappointed with myself for wasting all this time and effort for it to look SO bad. Any advice is so much appreciated. Thank you. ❤️
