Here’s another garter intarsia ornament, a plain Christmas ball with band around it, which was knitted from side-to-side. The ball is shaped by increasing or decreasing only at the edges. The colors in the band just jog over and back to make its curved shape.
If you compare it with the drum (Day 10) you can see the difference that internal shaping makes. I shaped the drum by increasing and decreasing inside the outlines of the drum. That method moved the red body and gold rims of the drum in a curved shape, without creating jogs. The drum was also knitted side-to-side.
