I have to agree with the others, there is no place for your eye to rest. But you know, we all learn from our mistakes. You should see the scrappy Christmas quilt I am working on. I will post a picture when it's all done. I have a lot of small pcs of Christmas fabrics and wanted to use some of them up.
But definitely finish the quilt, if it's not too much trouble add the sashing around each block then, I think, it won't look so bad, it would make it a little more pleasing to the eye. Or, again it would mean taking it apart, use the blocks to make table runners and placemats. I've done quilts that I really didn't like, sometimes I took them apart right away and reworked the blocks but other times I just put the top away because I was so disgusted with myself and after a while took it out and did something with it.
Good luck on whatever you decide to do.
