Right in your own backyard! Wear big woolly sweaters, light a fire, and roast marshmallows, just like in the lodge. The gifts could be things she'll need to learn to ski, ski gear, tickets for lessons, or coupons for lodges or even ski passes. You'll serve hot chocolate and maybe all hang out in the Jacuzzi afterward and reminisce.
Get some knit fabric and cut tiny sweater shapes. Get some wood-grain paper or contact paper stuck onto lightweight cardboard and cut out skis. Hot glue first the skis, then the sweater, to the front of your invitations. Cute! Send your guests home with packets of hot chocolate mix you decorated.
