Next time don't cut your fabric for the borders. Instead open it out and lay the blocks on it to audition them. That way you can always use the fabric for something else if you don't chose to use it for strips. You might try a darker brown, or a lighter tan for a border.
If you don't have the fabric yet, take your blocks with you to the fabric store and lay some across the bolt and look at it. If you think you like it, then open it out and lay more blocks to make sure. Ask the clerk to help you chose. They want the sale so usually will help, if you go in at a time when they aren't busy!
