The ways suggest are the ways most people do them and the way you kind of have to do them if you go with a 60 degree scallop, which some people say look better.
If you are going to do 45 degree scallops thin I suggest a 45 degree router bit. Cut a bunch of 3/4" x 3/4" x 7'' pieces of wood. Run the 45 degree bit on one side smack dab in the middle of the 7" section. Then cut the 7" length up on the miter saw.
Here's what the pieces will look like:
Then all you need to do is cut 2 45 degree into the top of your blank to make a point and glue the piece on. Rotate, cut and glue till your hearts content. This is really the most headache free way to go.

Unfortunately I couldn't find a 60 degree router bit that was at least 3/4" wide.....
But here's a 60 degree scallop with metal I did the hard headachey, glue my fingers to everythig way:
