Headlining finishing help

[HenrysCat]

Hi all, I have installed a new tongue and groove headlining without proper planning (doing this on a tight budget, spent about £40 so far) I started from middle and went out and now I have reached the edges i'm stuck, if you look at the first photo the panels meet nicely at the end where the fire blanket is, as you move down you can see in the second photo a large gap opens up, this tapers off towards the bow and the panels meet nicely with the side again, there is nothing to fix any more panels to and I am struggling to think of way to tidy this up.
Any thoughts?

My suggestion: Glue a few additional small wood blocks of the correct size to affix another strip. Scribe that strip to the cabin sides (either by offering it up and drawing a parallel line to the curve with an improvised tool or by cutting a template out of card, plastic sheet, ‘corex’ etc. and using that). It may never be completely aligned, so a piece of flexible flooring trim might help cover the cut edge.

Or maybe I’m missing something?!

I assume you want to fill in up to the line across the carpet type material. It also looks like you have a groove at the bottom of the last piece you fitted. I would get a thin piece of cardboard and slip in the groove and make up a template. you can then make up proper piece if it is wider that 1 plank in places cut the second plank and glue the the tongues in to the groove of the first part, and trial fit. Fashion some small blocks to fit between T&G and the GRP, you may need to cut back some of the carpeting. Stick the blocks and T&G with something like CT1 or sticks-all. If you glue the T&G into the T&G you have already fitted you may not need many extra fastening points.
