Blocking nightmare

So, I knit my first triangular shawl and realized when I blocked it that I had bound off the edge too tight and it went from a triangle to a bizarre alien misshapen horror. I fixed the bind-off and it matches, but now it is acting permanently misshapen. Any ideas on how I can get it to bounce back? I used worsted superwash merino.

Thanks!

What fiber is it made from? Usually you can just rewash/block it and it’ll be fine.

Yep, just rewet it and reblock how you did it before.
