What do I do with the extra fabric from a fleece tie blanket?

Id suggest putting them in the middle in some form of a quilting pattern using those pieces. Otherwise you could make "yo yo"s out of them;they're super easy (I think Clover makes a yo yo maker.) The yo-yo is the flower and you could cut out leaves and stems from some green fleece. Like maybe one in each corner? I really like you color combination!
