In Need of Opinions

I finally sat down and put the Things Quilters Think Blocks together. It is apparent that this was an evolutionary quilt. I can think of several points along the way when a cohesive plan might have made it seem a little less jumbled. I don't mind jumbled, but it does have me stuck on what to do with the borders. My fabric stash is not as extensive as others, so finding the right shade of a certain color never seems to work out for me. So although I do like to use what I have, I'm not opposed to buying something new. I see a lot of red in the quilt, but wanted to try to tie together all the different fabrics. I pulled out several multi color prints on black, because those are supposed to work as neutrals you know. I read it in Gwen Marston's last book, so it must be true. I tried those out with both red and pink. I also tried some mottled solids, thinking that might calm down the variety of blocks a bit. I really had a darker color in mind, like the purple from the center square, but the closest thing I found was a fat quarter of the purple on the left side. Maybe I should just find out what that purple is and order some of it. It came from a sewing themed charm pack, I'm sure I have the label somewhere or other. So, votes, opinions, options? Help me out please. This is my May UFO, so I have only two more days before I'm supposed to cross it off the list.
