OK- I've seen some good suggestions on this forum as to how to PREVENT quilt bunching/puckering... but that ship sailed yesterday, and I machine sewed my final quilt border (before binding) with several bunches/puckers (are they the same? Can't they just combine the terms- buckers? punches?)

ANYWAY, my question is... AFTER you have the buckers, what do YOU do- just ignore? Take the whole border out and re-start (please say no)- ? And wouldn't it just happen again- ?
I do not have a walking foot and am considering buying it if it REALLY will help in the future... but they are PRICEY!
Thanks for your help!
