What beautiful curves! They're easy, too, once
you know the right sewing techniques.

I know, I know, curves are problematic, whether you use straight stitching or free-motion. Many people who sew and quilt avoid projects calling for curved piecing for that reason. Who needs the stress?

Learning how to sew a quilt with curved piecing takes practice. All sewing techniques do. But experienced quilters know that some simple tricks can also make it easier to piece curves.

Once quilter Angela Pingel fell in love with the Drunkard's Path, she knew she had to figure out a way to make piecing curves easy and fast.

In her new book, A Quilter's Mixology: Shaking Up Curved Piecing, 16 Projects Using the Drunkard's Path Block, Angela reveals her sewing technique for curves–and it's not all about the sewing machine.

"The trick is to ignore the fact that you are sewing a curve. Pretend you're sewing a straight seam. Mind over matter can really help you sew a curve. And, truly, when the diameter of the curve is large, you practically are sewing a straight line," Angela writes. "Make sure the section of the seam where the needle is piercing the fabric always has the ¼" (6mm) seam allowance, and forget about the rest."

Here is Angela's method for piecing curves quickly and easily:

1. Mark the center of each piece along the curved edge (both convex and concave). To do this, simply fold the piece in half and give it a quick press just at the curved edge (fig 1). Then use one–yes, just one–pin to pin the convex and concave pieced together at the center, right sides together (fig2).

2. Sew the pieces together in two steps. First, align the two pieces together along one straight edge of each (fig 3), and sew from that edge to the pin at the center, easing the two pieces together (fig 4).

3. Stop. Trim your threads, and repeat from the opposite side (fig 5).

"I find that this method give me really clean ends to my quarter-circle curves, which is very helpful for the patterns that require precision," writes Angela. "Plus, sewing to the middle each time gives me a chance to double check my first seam allowance when sewing the second half. No one is perfect, and sometimes a bit of re-sewing is necessary."

If I were you, I'd practice on some "ugly" fabric or muslin a few times to get the hang of it. Then dive into the 16 gorgeous quilt projects from A Quilter's Mixology.

  1. I am not avoiding curves, just haven’t done any yet – still on HST’s as i’m a newbie…. but my mum used that way of sewing curves like facing on dresses & fitting sleeves…..she doesn’t quilt so i wonder where she learned it…..

  2. I used to be intimidated by curves until I sewed a whole quilt of curved blocks. I loved the tip to iron to find the middle. To me, the trick in sewing a curve is to pin, pin, pin! It is exactly like sewing a puffy sleeve in dressmaking. I pin the middle like Angela, then pin the straight edge and pin the middle of the first side of the curve making quarters. Then pin the middle of the quarters making eighths. Keep pinning until you have a flat straight seam. The material will be all wrinkly on both sides of the seam line but flat where you have to sew. As you sew, remove pins and rearrange the excess fabric out of the way. As Angela says, you are really just sewing a straight seam after all your pinning! As a general comment, quilting is as much pressing and pinning as it is sewing.

  3. No, I don’t shy away anymore. A few years ago, I decided it was time to tackle something new and took on curves and a double wedding ring. Patience and determination saw me through and I know they only look hard. They really aren’t.

  4. I find an easy trick is to press as directed, pin the two layers together at that center crease with the concave piece on top (think cave in for which curve is which). No more pinning required, your machine just feeds this together perfectly. Sew a tad slower than straight line sewing.

    12 drawer, this curved seam technique has been used by dressmakers forever. That’s how I knew to sew my pieced curved seams for a quilt.

  5. Oh I have read your post and you know what I think after reading it ? it just give directions to go out and start work on a Drunkard’s Path quilting. It’s just kinda perfect post, keep doing your inspirational work.
