In previous posts I showed you how to make a bias tape, how to make a continuous bias tape and how to sew a bias tape. Today I’m raising the bar – I’m going to show you how to sew bias tape binding on a curved edge 🙂
How to NOT bind curved edges
If the tape is cut on the bias it will adjust to sewn curves, right? Yes and no. Sewing it without prior preparation can be a challenge. Well – the milder the curve, the easier the task is, but look what happens when you try to sew it into tight curves.
One part of the project is being stretched the other eased in, the whole project is deformed. Has this happened to you before? Although ironing the project probably would fix it a little bit, it’s not a good solution.
How to bind curved edges properly
It is easiest to sew the bias tape using first method – sewing two sides in one go, you just need to make a small modification.
1. Mark the beginning and end of a curve on a bias tape. Shape the bias tape (folded in half) using an iron. Simply pull the bias tape, making the curve and press it with the iron to preserve its shape.
2.After such treatment the bias tape adjusts itself to the project, and sewing it is much more enjoyable. It’s simple, isn’t it?
You can see the difference with the naked eye (none of the pieces were ironed):
OK, and “what about the second method?”, you may ask. We don’t always want to have stitches visible, and sewing first one side, we can decide to use some other way to finish it.
It’s more difficult, but with a little patience it can be done. First of all shape the bias tape as in the first method. Secondly sew with short sections, adjusting the bias tape to the curve. Sew, stop with the needle in the down position, adjust the bias tape, and continue sewing. Try not to stretch the bias tape and definitely do not stretch the curves. With the tape shaped prior to sewing it should go well.
