To Finish?

Always needing to keep my hands busy, I have been doing a lot of hand stitching.  I have collected many different variegated threads, pearls and flosses that I particularly enjoy working with.  Variegated adds interest to the texturing.  I brought Sue Spargo's collection of Wonderfil #8 Perle cotton into StitchCraft this year and love it!

I taught a Gelli Printing class this past week in the shop.  It was a fun morning of play!  While making samples I found myself stitching one of them.  Now covered in seed stitches, I am trying to decide what to do with it.  Do I finish it as a little piece or add it to something larger.   I have made many small fiber and stitch collages lately and they are starting to stack up.  I took a class with Liz Kettle at Quilt Market in May and she mounts them individually and sells them as small pieces of art.  
How would you finish this?
