Bohemian could be focused towards the colours and the print of the fabric and/or the actual quilt pattern.
My suggestion would be for you to get her involved, so that you feel good about what you are making, knowing that it is something she likes.
If she lives near you, perhaps she could come over and look at pictures on your computer (Mr. Google will be pleased to help! Otherwise, she could email send you some pics or links. Even better still would be to let her help you pick the fabrics.
Good Luck!
