Starting a Ribby

Hello everyone. New member here, starting my first Ribby Cardi for my daughter. I'm going to use a cotton blend (Berroco Luxe, in Lavender and Raspberry-- she wants itch-free guarantee), after making sure the row gauge works for the raglan sleeves (the spi on this is 5, but that's OK, she's small). Question--Has anyone done the raglan sleeves and body by putting them all together on 1 needle to finish and do the neck? That's how I usually do raglans, seems easier that way. Enjoy looking at everyone's cardis. Such lovely color combos.
