It's warming up here in Texas and I'd like to make a popover sundress for my daughter. I'm wondering - do you think the straps need to be cut on the bias... or could I get away with cutting them on the crossgrain? I don't have enough fabric to cut them on the bias (maybe 1/4 yard) and I'd love to get by using what I have. Will it work? Or do you think they won't lay right?
