I often use my little hole punch and add a tiny bit to a corner or glue a little remnant horizontally or vertically across the card.
For Christmas last year, I used a full length to hang a custom-made decoupaged canvas. I used some glittered letters and some Christmas scrapbooking papers to create some holiday-inspired decor.
I googled this company and there are many, many websites that sell BasicGrey fibers - many times on sale.
Let your imagination go and create something beautiful and personalized!
