Brodissime

I just spent three weekends on a woven wall hanging—first time trying tapestry—and I was so proud. Then I trimmed the fringe to even it out and cut one warp thread too short. Now the whole bottom edge is pulling weird and I want to cry. It's not totally ruined, but it's not what I pictured. How do you decide when to try to rescue something vs. just scrap it and start over? I'm new to this and I have no idea if fixing it will make it worse.
