you can make a neat join using something called pro finish carbon... EC sell it.
I had to do a number of these so I made a feature of it... have you considered opposing weave? All you need to do is lay one side with a very neat line, lightly glue it down... then the other side simply overlaps as you dont need a neat line for this one.
here is what I did... pegani do this on the bonnet so one half the car goes one direct, the other half the other way, looks fantastic IMO
I've used the pro finish a couple of times but does the resin holding the pro finish not show up in the finished part if you turn it over to get the opposing weave? Nice idea and may give it a go
