Disappearing Nine-Patch

Had a chance to escape last weekend!! Went to a small retreat down in Torch, OH. Had a wonderful time with some pretty awesome quilting friends!!! Wasn't sure what I wanted to take to work on? I wanted "mindless" sewing! I needed to regroup and refresh, not only my body, but mind also! The BOW/WOB/brights 9-patches have been sitting here. I had started cutting and resewing them but just didn't have the stick-to-itness I needed to finish, so to retreat they went! I've also added a solid black border and and trying to decide what to do for the last border(s)????? Got a few great suggestions from the other quilters at retreat, now have to decide! What do you suggest?????? (from 9-patch to a disappearing 9-patch)
