So this is not quite free, but very close. My cost was the printer ink and copy paper. I have figured this cost to be about 4 cents per page. I didn't need a lot of gift wrap, just enough for one small package and one slightly larger package. I ended up using 4 sheets of printed paper, for about 16 cents for both gifts.
Those gifts that I bought at clearance and semi-annual sales now need wrapping. The above gift is part of a birthday package for someone who is special to me. Wanting a chic and classy look for this birthday gift, I decided on a black and white color scheme. (By the way, this is very inexpensive to do with home office supplies.)
Using free clip art, I made this pattern on my laptop for printing onto a sheet of paper. In my experience, Apple Pages seems to work better for cut and paste of images than MS Word, so it's what I have used here and with other printed images.
The small gift used 3/4 of a sheet, while the larger package used 3 sheets, with strategic piecing to minimize visible seams. The most obvious seam runs across the center of the package and shall be concealed with ribbon.
I did invest some time making the pattern, but I considered this fun, down time. In addition, I now have this pattern stored on my laptop for future use.
For a price comparison -- I could have bought some gift wrap. Even at the Dollar Store I would have spent $1 for wrap, and likely would have used about 1/3 of one of their small rolls, or 35-cents' worth. Printing gift wrap at home was about half of the price of the least expensive option for me, meant that I could skip a trip to the store, and was an outlet for my creative energy. A win all around! And I don't have any leftovers lingering in a closet, as I printed only what I needed.
