Universal isn't wrong if that's all you have, but I think there's better choices. I use a microtex (aka, sharp) instead of a universal needle. Universals have a slightly rounded tip and the microtex has a sharper, thinner point so it's perfect for piecing, appliqué, and quilting. Here's some info on how to choose and the differences between needles.
