Mastering Machine Binding

Today, we’re going to show off our favorite BERNINA accessories to help you machine bind your quilts with ease!

See the tutorial to create the Sea Birds Baby quilt here.

Baby Quilt Binding Tutorial

I tend to be very particular about how my quilts are bound. Machine binding always felt rushed to me and for the longest time, I had a hard time finding a way to do it and have the final product look clean and professional instead of looking like I took the easy way out. This method has changed everything!

My preference is for 2.5″ binding so that’s what we’re working with today. Others may prefer a skinnier or wider look—it depends on the quilt/batting, the way you attach it, or just aesthetics. Play around with different widths on different projects but 2.5″ is a great place to start.

Instructions for Machine Binding a Quilt

1. Do the Math

Calculate how much binding you need. If binding is still new to you, keep reading. If this isn’t your first rodeo, skip along to the next section.

To calculate binding, add up length of all sides of your quilt. Recognize that despite our best efforts, quilts aren’t usually perfectly squared up so take the time to measure each side, in case something got a little wonky.

For this baby quilt: 35″ + 35″ + 48″ + 48″ = 166″

Add 10” to accommodate corners and some overlap for joining at the end.

166″ + 10″ = 176″

Now divide that number by 42. That’s your average width of fabric (WOF) for most quilting cottons once you cut off the selvedges and whatnot. You likely won’t get a whole number so round up. That’ll give you the total number of strips you need to cut for your binding.

176″ ÷ 42 = 4.19; round up to 5

To calculate how much yardage you’ll need for your binding, take that number of strips and multiply it by the width of your binding.

We’re using 2.5″ binding today so: 5 x 2.5 = 12.5

2. Cut

Now you’ll cut your strips. There are two different ways to cut binding; straight of grain or bias. For most squared quilts (with 90 degree corners), straight of grain is fine. You definitely want to use bias for anything with a curve because the bias cut stretches and allows you to finish those edges without puckering or weirdness. Some people swear by bias binding for everything but it is more complicated to cut. We’re going to keep it simple today and stick to straight of grain.

For straight of grain binding, have your fabric folded in half, with selvedges together (a.k.a. how fabric comes off the bolt). Using an acrylic ruler and rotary cutter, cut as many 2.5″ strips as determined by your math wizard skills established in the last step.

Don’t forget to trim away the selvedge from your strips!

3. Piecing & Pressing

Overlap strips at a 90 degree angle with ¼” overhanging.

Master Mchine Binding step 1

Stitch on the 45 degree diagonal to join and trim away the excess and dog ears.

Master Mchine Binding step 2

Repeat until all your individual strips become on very long strip. Press seam allowances open and press the whole piece in half horizontally. Now we’re ready to start attaching!

4. Attach

Using your machine’s walking foot, start attaching binding in the middle of a side. Do not start at a corner! Leave a tail of binding before you start stitching (at least 8″) and secure your stitch when you start.

Master Machine Binding step 5

Stitch your binding down using a 3/8″ seam allowance. When using the walking foot, align the raw edge of your quilt with the edge of the foot and set your needle position at +5 (furthest position to the right of center).

Master Machine Binding step 6

When you reach this 3/8″ point, pivot the quilt to stitch off into the corner at a 45 degree angle.

Master Machine Binding step 7

Take your binding and fold it back to get a 45 degree fold.

Master Machine Binding step 8

Then fold it down to match raw edges along the next side.

Master Machine Binding step 9

Resume stitching, again at a 3/8″ seam allowance, starting 3/8″ from the top edge. Repeat this process for all corners until you get to the side you started on.

Master Machine Binding step 10

Stop stitching when you have at least 12″ before the point where you started. We’ll need to join these loose ends together!

5. Join binding ends

Make sure that one of your tails is already cut at a 45 degree angle.

Lay tails of binding out to see where they overlap.

Using the marking tool of your choice, draw a line exactly where these tails meet.

MasterMachineBinding join 3

Mark an additional 45 degree line 1/2″ away from the first line you marked. This extra half-inch will accommodate for your seam allowances when you join the tails together so be sure you’re placing it in the direction to add length, rather than take away! Since you can barely see my original line in this photo, I added a dashed red line just to be clear.

Trim away the excess at the second drawn line.

Using a 1/4″ seam allowance, join these two loose ends.

Finger press your seam allowance open.

Fold over and finish attaching it all down!

6. Wrap & Clip

Next, wrap your binding around to the back side pin in place. Using binder clips or Wonder Clips for this is a great option too—no one likes getting stuck with a rogue pin!

Master Machine Binding step 11

When you’re folding your binding back, make sure this folded edge covers the stitching line where we just attached the binding. This is key!

7. Stitch in the Ditch

Switch from your walking to the Edgestitch foot #10D and engage Dual Feed; the Dual Feed is the real superhero in this situation. We’re sewing through a lot of materials now—the quilt top (and probably some seams), batting, backing, and two layers for the binding. Dual feed is going to make sure all of these layers move smoothly and evenly without shifting or puckering.

BERNINA Edgestitch foot #10D

Using a top thread color that won’t contrast with your quilt top, stitch in the ditch with the right side of your quilt up. I like to start in the middle of a side for this as well but you could start in the corner on this one!

Master Machine Binding step 12

The guide in the center of your edgestitch foot shows you exactly where your stitching is going to fit. Scoot your binding right up to that guide and your seams will fall so close to the binding, they’ll be nearly invisible in the finished project!

Master Machine Binding step 12

When you get to a corner, use your free hand system to slightly raise your presser foot, leaving the needle down in the quilt, and rotate the quilt 90 degrees. You can also set your hover mode settings to automatically lift your presser foot to an appropriate height for this when you stop stitching. How cool is that?!

Eventually you’ll get back to the spot where you started. At this point I like to overlap my seams by just an inch or so to make sure everything’s secure. Hit your thread cutter and you’re done! Check out some close-ups: the bobbin thread just barely grabs the edge of the binding on the back and the top thread is nearly invisible from the front.

Binding by hand is classic but takes hours. If you’re like me, and antsy to throw that new quilt in the washer, this is a great way to get a consistent and professional finish and fast forward to that warm and crinkly final product. Enjoy!
