I do things like that all the time. If you have enough fabric left, rip out the border and start again. Usually when I make a mistake like that, I don't have enough fabric to change it out. I have to sew little pieces together to make the strips and then it doesn't look so great. But we've all done things like that. You were probably thinking one step ahead and not thinking about what was at hand. That's how we learn. And boy have I learned. And I think I'm going to be learning for the rest of my life.
