Sue, I kind of agree with KWhite. My husband doesn't "do" color combinations either, so I've stopped asking his opinion. But it's funny how he really likes what I do AFTER it's all put together and finished. Just do what you know you love. :D
And I know what you mean about the helpful people in the LQS. I have one like that and I sooo rely on their help and I feel giggly when the color/fabric pattern and everything comes together nicely. Good luck on your class and don't forget to show pictures!!!!!
