It's probably just a good idea for not creating extra waste, but it may also be that the host has to pay extra for trash pick-up, as one of my friends does in a rural area. A "green" wrap, such as a receiving blanket or reusable fabric bag is an idea whose time has come (except for companies like Hallmark!). For several years now I have added a few more Christmas bags to our collection: just pretty seasonal fabric, sewn like a pillowcase with a pinked edge on top and tied with re-usable ribbon. My family loves it. They arrive with their gifts unwrapped and use the "Santa bags" - quick, easy and cheaper in the long run (while they stay in the family). Also, I figure if I need any of that fabric for a quilt, I wouldn't hesitate to raid the supply, since it's all from my stash.
