Sistered joists

I am designing a long L-shaped deck, that wraps around the corner of my cottage. Along the front of the cottage, Joists will hang from a ledger. Where the deck wraps around the end, I have in mind running joists the same direction, over a beam perpendicular to the end wall of the cottage.

From the front edge of the deck to the back of the 'foot of the L', at the wrap-around, is about 23' - too long for single joists. I have in mind sistering them on a beam. This would let me run decking all the same way,
which I'd prefer, and avoids having to put a ledger on the side of the house, which I'd also prefer.

My question is what to do about the sistering for the last pair at the rim of the deck, where the joist would show. Double the inner sister to where it would but the outer sister, to fill in the space and make the outside joist look like one? Or there is something cleverer than that?

Thanks!
Dave

Welcome to the forums! No, it looks like you have the right idea. Attach the band to the other bands and make it a double all the way, offsetting the joints.
