I think all those together would go great!!! I love bright quilts. If she has picked out the fabrics, you know she is going to like it. My daughter picked out 4 fabrics for a quilt. The colors do not go well with each other at all, but she is the one that picked them out and it's been a few years. She still LOVES the quilt. The fabrics she picked must make her happy and that is what matters.
So I hope you make the best of making the quilt. You will make one happy customer!!!
