I decided for my patio a love seat/sofa combo would work better than the sectional. It was easy to make both and modify the plans to have arms at both ends of the pieces.
Getting inexpensive cushions was a challenge. I ended up getting IKEA HÅLLÖ cushions. I added more foam to the back cushions as was suggested in another post since the IKEA cushions were a little flimsy and tend to fall through the back of the sofa. I might add some bigger cushions at some point
