out the top of my head, I can think of two metods:
1) fill a cup or something with folded paper pieces numbered from 1 to n=7,9, and pick one. this gives an uniform distribution.
2) use a 1d6 or 1d8 (it depends on if you want an 1d7 or 1d9) and roll it. call the result k. then flip a coin: if it gives, say, head, add 1 to k.
