Project: Do you really need to cut bias tape on the bias?

not on the bias

I did some experimenting and my answer is, Yes. And . . . No.

see how it's all bunchy?

As you can see in these first two pictures, I did not cut the fabric on the bias because I didn't have enough of the solid. I thought I would make do with the little that I had. It didn't work and I ended up ripping off the trim stitch by stitch.

So when adding bias tape to any type of curve, you really do need to cut the fabric on the bias. I ended up buying some fabric and using the diagonal line of my cutting mat to make that perfect 45 degree angle.

on the bias

It turned out much better.

But I had to buy a 1/2 yard of fabric to get nice long strips (I don't like lots of seams on my bias tape). I needed about 3 strips for this project and had two bizarre triangle shaped pieces of fabric left over. What a waste. If you're like me and you rarely use bias tape around a curve, I recommend that you just buy a pack of bias tape in a color that's close enough. You'll get about 3 yards for less than $3. That's much less than the cost of 1/2 yard of nice quilt-weight cotton and you won't have fabric left over -- just extra tape to keep on hand for future projects.

If you're using the bias tape for a hem (even a sleeve cuff), not cutting on the bias is going to work out just fine and it won't waste so much fabric.

Edit: One of my friends just asked me what bias tape is. I forgot that not everyone who reads this sews! My plan wasn't to make Project: Project all about sewing but the weather has had other ideas and I've done little else since January.

Anyway, bias tape is that orange stuff in the pictures. It is basically 2" strips of fabric with three folds that create a clean little way to cover up the unsightly edges of a project. It is usually used for binding the edges of quilts. Quilt bindings need to be cut on the bias so that one single thread of a piece of fabric isn't the one getting all the wear. If the fabric is cut on the bias, or the diagonal, then many threads make up the edge, prolonging the life of the binding. Quilt binding does not need to be cut on a true bias (the 45 degree angle); it just shouldn't be cut on the square (or parallel with either direction of the weave of the fibers).

For clothing purposes, I cut my bias for the experiment on the true bias so that it would have the maximum give and stretch. But like I learned, if you're just adding some trim to a cuff or a hem, any way you cut it is going to work.

Hope this helps!

Thank you for doing this experiment. Now I don't have to! I've been wondering about this. Whatever you are making looks really cute.

Have you heard of continuous bias tape? It looks a little tricky to learn, but I've heard once you learn it it's pretty great. No wasting fabric.

As part of the dress I've been working on in the pictures, the seller gave a tutorial on making bias tape from a fat quarter. It's actually really easy but you're going to have lots of seams and I just don't like all the seams. I'm picky!

Thanks for the link.

I'm trying to buy some buttons for that dress to cute it up but I'm having some problems. I should be finished with it soon. I'm loving how it's turning out.

I'm so glad you did the experiment. I'm going to be making a skirt and using bias tape for both the top and the bottom. It's REALLY good to know that I don't need it on the bias for that. I, too, am not a fan of the seams or spending more than necessary on the fabric. If it's all right with you, I'm going to link this post of yours with my bias tape lesson overview?

Chuka mentioned continuous bias tape.

Yep, it does really only matter on curves. I see lots of quilt bloggers insist that quilt binding needs to be bias to last longer, but the 70 year old lady who runs my local quilt shop says that's bunk. I figure she's been around long enough to know from personal experience!
