I have an idea that no one has yet mentioned. Make scrappy twine from the leftover strips. Cut them along the fold so they are just over an inch wide and go to it. Here's where I found this idea on Pinterest.
http://mypoppet.com.au/makes/2014/04...ric-twine.html I have learned that strips can be too long - they get twisted around and I need to stop and untwist, but I am really enjoying this method. I will use it to tie up Christmas gifts. Simple white or one color paper will show off the fabric twine.
