Use the Circle to Find NNS Chord Progressions

I have constructed a circle of numbers outside the circle of fifths. The numbers correspond with the scale notes, so that if C is at the top of the circle, a 1 is above the C; above the D is 2; above the E is 3, etc.
The numbers are on the outside and do not move. The circle of fifths is on the inside on a grommet, and I can rotate it so that whatever key I put below the 1, the chords in that key are easy to find. So if I am in the key of D, I rotate the circle of fifths until the D is at the top, below the 1.
I then easily can see that B is the 6 chord, etc. It works for every key, and is a helpful aid for persons learning to play music using the NNS numbers, rather than chord names.
