Winter Wedding In June

Hello and thank you for spending time to read this. We (my fiance and me of course) are getting married the last weekend of June and we would like a winter theme. We have chosen ivory and sage as our colors. The bridesmaids will be in sage. We thought maybe for the gift table we`ll have a Christmas tree to put the gifts under.... Those are the few ideas we have besides decorating with snowflakes. Any other ideas anyone??
