What stitch could I use to make this tea candle holder a bit taller?

The pattern has some extended double, half double posts and single stitches in reverse, so I’m not sure what stitch would blend in well. The pink is the last row, so to heighten it would be somewhere below the pink. Any suggestions? Thanks!
