Birthday And Easter Celebration

This year its double celebration for us with Easter and our son`s birthday falling on the same date. We are throwing a small party. Inviting all my son`s friends from school and neighborhood. Needed some help in selecting the centerpieces needed for the party decoration http://www.flowerscanada.com/occasion/easter Since its both birthday and Easter party I was thinking of getting Tulip flowers. What do you think. Need advice.
