that is great! i never thought about doing that. a few other things i have heard about:
using fabric bags
reusable gift bags
leaving santas gifts (or most of them anyway) unwrapped
tying ribbon on to an unwrapped gift (great for bulky or odd shaped gifts like bikes)
and i love this one, although it is not reusable, put gift in box, wrap with 15 thousand layers of duct tape masking tape and or book binders tape. Great if you dont care that the box will be destroyed, but the best part is watching them try to open it : ) oh the days of being the older sister. btw this really only works well with small gifts, unless you want to pay more for the tape than the gift
if it wasnt for the kissing tradition, no one would care about mistletoe.
To live is to die slowly, love fully, breathe deeply, laugh uncontrollably, sing loudly, dance wildly, take no one for granted, smile when you want to cry, raise others up and be raised. Never let what you cant do, stop you from doing what you can.
