Tutorial: How to make bias tape

As I mentioned recently, I think bias tape is wonderful stuff. It’s a terrific help if you can learn to make it yourself. Yes, it’s a bit time consuming, but the possibilities are pretty endless for prints and patterns, it’s less expensive, and best of all as far as I’m concerned, you can make tape to match your fabric!

If you’re not really familiar with bias tape, it’s basically a long strip of fabric that’s been cut on the bias of fabric. Because it’s cut on the bias, it stretches, which makes it really easy to sew around curves and such. The strips of fabric are folded so that you can sew them to enclose seams neatly.

So here’s my method. Nothing novel, but I thought it might be handy.

You’ll need:

  • a piece of fabric to use for your bias tape
  • a Clover Bias Tape Maker. These come in various sizes, I find 1/2″ useful.

Step 1: Cut yourself a rectangle of fabric. How much tape will you get out of it, you ask? First, figure out how many square inches your rectangle is by multiplying the length by the width. Now divide that number by the width of the strips you’ll be cutting. That will give you a rough approximation (I say rough approximation, because you’ll probably discard the corners of your fabric).

Step 2: Now you need to find the bias. To do this, simply fold the fabric so that the edges meet to form a triangle. Mark the fold (I did this by pressing it, so the pressed line is the bias grain).

Step 3: Mark off strips along the bias by measuring equal distances from the line you marked. Your strips should be twice the width of your completed bias tape. So if you’re making 1/2″ tape, your strips should be 1″ wide. (I know, mine are a bit sloppy, but silk charmeuse is slippery. It’s easier on cotton or the like). As you get to the corners, your strips will become very short. It’s probably best to just discard the corners rather than worry about sewing all those tiny strips together.

Step 4: Now cut out your strips. You’ll notice that the strips are stretchy if you give them a tug.

Step 5: Trim the ends of the strips so they’re flat.

Step 6: Place two strips at 90 degree angles with the right sides together, lining up the edges. Sew diagonally across, as in the photo. Continue sewing all the little strips in this way to form one long strip. Make sure they each are sewn the same way, so that all your seams go in the same direction in the end.

Step 7: Trim the pointy little seam allowances on each seam.

Step 8: Press the seams open.

Step 9: Now to use the fun doohickey! Feed your strip evenly through the bias tape maker. There is a little metal bar you can gently pull on to help guide the tape. As it comes out the other end folded, press it down as you go.

And you have bias tape! This is single-fold bias tape. If you want double-fold bias tape, you just have to fold it in half again and press.

And here’s what your seams will look like from the outside. Diagonal and pretty and neat!

Perfect Tutorial! Usually I see bias binding how tos telling you to use a full yard or more of fabric, which if you ask me, is not entirely practical.
Oh how I love bias tape! So many uses, so little time.

Thanks and cheers.

Anna Allen says:

i didn’t know there was a bias tape maker! wow. and here i’ve been doing it the hard way all these years. thanks!

Liz says:

Great tutorial – I wish it had been around when I had to teach myself how to make the stuff.

I totally cheat when cutting and use my rotary cutter and ruler. Most quilting rulers have 45 degree angle marked and I just zip through the first cut after lining that up. After that, I just line up the edge and cut the desired widths without having to make marks.
Rotary cutters make it onto my short list of best inventions ever! :)

I have to agree with this statement!

i love making my own bias tape and now I know what that little “thingamabob” is for! there was one in my grandmothers sewing supplies that i inherited and i had no idea what it was. woo hoo!

Sarai says:

So glad this is helpful for you guys!

Liz, that’s a great method with the rotary cutter and ruler, I don’t know why I’ve never thought of that! I’m going to give it a shot next time.

[...] Sarai Mitnick from Colette Patterns shows how to make bias tape.  Sure, you can buy it in the neat little packages at the fabric store, but your choices there are fairly limited and making it yourself is actually a very simple process.  Go to the tutorial. [...]

Rabid says:

After making bias tape for a placemat all weekend, and trying to convince people it’s not hard, I run across a tutorial :D I’ll be linking it, assuredly.

It’s not that hard to make bias tape even w/o a bias tape maker. Fold in half lengthwise. Press. Open and fold edges to middle. Press. Tada :)

Yellie says:

Great tutorial and that little doo-hickey thingie is so neat!

Casey says:

Oh! I’m definitely going to buy one of those bias makers asap! I’ve been dying to get one for years, and now I have to. ;) hehe. Thank you so much for this tutorial. Now I have no excuse not to make bias tape. ;)

NoirGirl says:

Thanks so much for this lovely tutorial! It comes just at the right time, as I’m at the stage of my latest project where I need some bias tape to finish. :)

Jill Ison says:

oh my gosh I’ve been making bias tape without a doohickie all this time??? Oh I feel so dumb with my big ol iron trying to do it manually… off to the sewing store :) glad i came across your blog!

Sarai says:

So glad I could help turn some of you on to the magic of bias tape makers! They’re such a simple little tool, but such a time saver!

Julie says:

Thank you for the easy-to-follow tutorial. I lost my instructions for the doohicky and I’ve been wanting to try it out for a long time.

I needed a refresher in making bias tape and your tutorial was so helpful. I’m going tomorrow to purchase a bias tape maker – so much easier than turning under the edges on your own! Thanks much!

Thanks for the info on the bias tape. It sure has helped and I plan to make your web site my regular on my desktop.

Tracy says:

Thanks so much for the reminder, I appreciate that you took the trouble to set it out. Now I am off to make some bias tape.

I’ve been making my own bias tape for years… that little “thingamabob” will help tremendously… save burnt finger tips (I have been ironing each side over all these years!)… ouch!

this is how to make your own “bias tape maker” instead of having to purchase one…just in case anyone is broke like i am.

clf says:

this is a more efficient way to cut bias strip binding. it’s used by quilt makers (who have to cut a lot of binding!)
http://buzzville.typepad.com/buzzville/2006/03/cutting_continu.html

i have a clover thingee too, but i find that the binding sometimes comes out lopsided when it feeds out of the thing. i can’t seem to get it perfectly divided up. sometimes one side is thinner than the other

Sarai says:

clf, thanks for the tip, that’s a great link!

Mint Julep says:

Sarai,
LOVE your dresses! Here’s a tutorial you might like–there’s actually a much faster (and easier) way to make bias tape. Essentially, after you draw off the lines, you sew it into a tube, then cut and you have one long, continuous piece of bias tape. Brilliant! http://whipstitchlounge.blogspot.com/2009/03/ive-had-some-questions-about-how-to.html

Kay says:

Just to jump in the ring with another tip here, if you don’t have a bias tape maker, or if you do but you want to make double fold, you can use a ruler and a few pins nipped into your ironing board (just make sure the space in between the first nip and the second is the width you want your bias tape to be) run the tape under the pin and it will fold itself neatly, then run it under the iron. (It’s easier for me b/c I can set it up “assembly line” style, leaving the iron to sit and just pulling the tape underneath it. If you move fast enough, the iron will moderate it’s own temperature and then I don’t have to fuss with the iron or holding the tape maker down.)

Bobbie says:

Great tutorial! I have been quilting for awhile but have never made my own bias tape. The directions were so clear and concise. I always say you can learn anything from the internet. Thanks!

Yasmeen says:

I need to invest in that bias tape maker. It looks a lot easier than my regular method of steaming my finger tips from my hot iron being too close. Thanks!

Krystal says:

Whoa, so excited to see this little bias tape maker! I thought my only option was one of those electric ones, and I didn’t want to drop $100.00 on one. This little guy has such a “stick it to the man” attitude to it (maybe I should have called it a little “gal” :). Inexpensive, efficient and has history behind it! I love it!

Jude says:

Your tutorial was awesome……so easy. Thank you!
