Can I “frog” the beginning of a filet tapestry while keeping the rest?

This is my first crochet work ever, and I’m not sure why but my first 10 rows just aren’t very good. I’m over half way through now and the rest of it is pretty consistent\**,* but when I did a mid-crochet block to see how things were looking, the bottom/start is just noticeably looser + wider*. This won’t block out, I’ve tried.*

I know you can’t really frog from the start because of the stitch directions, but I’m wondering if it’s possible to literally just cut off the tapestry’s start, and slip stitch a replacement piece on. Or would the entire thing just unravel ??

As I’m new to crochet I don’t quite understand the physics of it all and what the consequences of cutting it would be.

To be honest I’m gonna cowboy it either way because I’m not gonna restart the entire thing and it’s gonna piss me off if it stays uneven, so I’m looking for advice before I just say F it and get out my sewing machine or something haha.

Thank you for any advice !!
