First I printed out the pattern from the Sew Bossi blog. and cut that out. I found two larger pieces of scrap fabric I had lying around for the carrier. I figured blue and brown were boyish enough for the Finner Bean.
Here's the carrier body sewn together and turned with openings left to attach the straps.
I didn't bother with the buttons. I may go back and add those later but for the sake of simplicity I left them off for now. Without buttons the carrier is also reversible.
Here's the back view of the carrier. Finn can't put it on himself yet and needed my help putting the baby back quite a few times. At last he seems to be enjoying himself.
