I'd pick a comfortable chair and trim all those little threads, being very careful to not cut a hole in any of the pieced quilt. I would probably press it first, so everything is laying flat, but not really sure about that.
Edited to add: I am ADD about trimming all those extra threads when just doing piecing, much less, if I had to wash the top before it was quilted. I quilt my own quilts on a longarm and have had to unroll to trim a thread when I could see it through the batting.
