Melt butter in large saucepan over low heat. Blend in flour and salt; cook and stir 1 minute. Gradually add milk; cook, stirring constantly, until thickened. Add velveeta and cheddar cheese; stir until melted. Stir in macaroni.
Pour into lightly greased 1 1/2 quart casserole. Bake at 350 degrees for 20 minutes or until thoroughly heated.
Notes: Kenzie loves this. The picture shows it with a crumb topping, but I omit this part.
