Depending on what the blocks look like, I may use a white. On the one I did for you, I used a white in the background and the beige might look ok. My thought is I would set them all up on the design wall and then audition fabrics to decide. If more used the beige/cream you requested, then I would go with that, if they used more white, I would go that direction. It all depends on how much cream/beige/white you have.
