With a little bit of practice I was able to match the texture on the existing wall. I found that the bucket scoop trowel worked the best as it has nice round edges that didn't leave marks in the compound.
Yesteday we got started on the painting. The new wall is lovely shade of Violet. The Halogen work light has been key for painting a nd spackling, even during the day. It makes it much easier to see the texture and whether you have good coverage.
