I just made 2 braid table runners. They were both so wonky! Bias edges are so difficult. I think my main problem is that I got lazy and didn't measure and cut my borders....I just sewed it on and then trimmed. I didn't even think about the bias edges. I ended up spraying them with Best Press (soaking wet) and pressed and steamed the heck out of them. They don't look too bad now after quilting and binding. I hope they sell at the craft fair so I don't have to look at them anymore.
Good luck with yours, AngelaS. Be sure to cut your sashing strips to size and use a lot of pins when sewing them on.
