Some of the interesting shapes can be used to embellish projects such as altered books, tags, collage or even your regular sized cards.
For example I noticed the left-over pieces I had after cutting some of these Tim Holtz Flourishes.....

looked like the oriental dragons you see on Kimonos.
With that in mind I put my scraps to use to make this pretty kimono card.
See how dramatic it is now, decorated with off-cuts.
