Think John Travolta and Saturday Night Fever, hot pants, floppy hats, tie dye, the "me" generation, and watch "That 70's show" a few times. Might get some ideas there. I would try to find some tie dye fabric (maybe in batik type fat quarters) and go on quilterscache for a block you think is appropriate. Good luck, and don't forget to show the finished round. Incidentally, I wouldn't use any solid bright colors that might clash with something else. 70's was more hippy than that. Streakers, blue jeans, etc. I know you said you were busy raising your kids back then, but I plead the 5th as to what I was busy doing. :P
