Christmas Eve announcement

My husband and I are waiting until Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> to announce our pregnancy! I'll be 13 weeks! I was wondering if anyone has any cute Christmas ideas as to how we can announce! His mom is going to be absolutely thrilled and i want to make it as special as possible for her, as she's been begging us for over 2 years for a grandchild!
