I'm so bummed!

My daughter and I basted the French Braid quilt yesterday and I have decided to stipple it.  It was painful to get on the floor but we did it.  I got to use my Kwik Klip tool to close the basting pins which really does save your fingers!  But...and this is where I am so bummed, the borders, the pieced borders are wiggly.  I'm not sure what I did wrong and now that I am done beating myself up about it, I need to figure it out so I can start quilting! If you have any ideas or suggestions, please let me know.  I'm thinking I will have to take apart the basting on the border bits and then unpick the join and take it in.  I don't know what to do!!!!!!  I always get these sucky problems.  Errrggghhh!!!!
