Weft-faced 2/2 twill draft

Drafting has never been my strength.  I am trying to figure out how to create the draft for a weft-faced rug in a 2/2 twill using 2 different weft colors in an AAB sequence.  The threading is a straight draw and the treadling is 12, 23, 34, 41.  I know how to physically set up my loom and to weave the rug but want the mental exercise of creating the draft.  I have been using Pixeloom but would be fine if someone could just post any 4-H draft showing the weft-faced AAB weft sequence.  I'm not sure how to notate the AAB rotations.  Thanks.
