I love making my own wrapping paper for gift giving and special occasions~I pick out some vintage paper goods from my inventory and go to my favorite Kinko's. Since I like to use lots of black and white or sepia pieces the trick for me is that I always use the color copier. It just makes the graphics pop while retaining the vintage paper feel. You can even reduce or enlarge the picture of your choice to add greater details to your wrapping paper. For my recent Soap orders, I took three vintage French bags an old Christmas song book and dictionary pages to Kinko's and copied away~
Old photographs are great to use also, you are only limited by what you can't fit under the copier!
