Starts and Stops and Quilts With Girlish Figures from the July 2011 issue of Machine Quilting Unlimited magazine



Dear Kimmy-I am having trouble keeping the side borders of my quilt straight as I go along and my finished quilts always seem to dip in at the sides. Why is this happening and how can I fix it?


Kimmy says- This is a very common problem with a super easy solution. Before we get to the fix, though, let me answer your ‘Why’ question and then I’ll tell you the ‘How.”


The most common reason that quilts ‘hourglass’ is because they were loaded on the machine at the incorrect width. This happens when the outer edges of the quilt are wider than the center and the quilt is initially pinned on the quilt frame at the wider measurement. Here’s an example: Let’s say I have a quilt that is 90 inches wide through the center. However, the borders of this quilt were heavily pieced and they ‘grew’ during the piecing process so, instead of measuring 90 inches wide like the center, the borders are 92 ½ inches wide. Because I am feeling rushed while loading this quilt, I do not take the time to measure it properly and am therefore unaware of the size difference. I load the top on the machine, smoothing that oversized border out nicely as I go and pinning it on at 92 ½ inches. Everything is hunky dory as I first start quilting, but after one or two advances I begin to see that my quilt is drawing in at the sides. This is happening because I’ve moved past that overly full border and am now working on the interior of the quilt, which is only 90 inches wide. This ‘drawing in’ effect will continue all the way through the quilt until I come to the bottom border, which will flare out again to the 92 ½ inch width, causing my quilt to look like it has a lovely girlish hourglass figure and ruining my whole day.


To avoid this, I should have measured the quilt in two or three places *in the center of the quilt, not the borders* as this would have shown me that my borders were just a smidgen too big for the rest of the quilt. To correct this problem, I would have pinned my quilt on at 90 inches and eased in the excess border fullness as I quilted, ending up with a finished quilt that was 90 inches wide from top to bottom. Pieced borders are not the only thing that causes this problem; you can also have issues with solid borders that were cut incorrectly and you can even create this problem yourself by stretching the edges of the quilt as you load it.


Now that we know the ‘Why,’ let’s talk about the ‘How.’ Once you’ve loaded the quilt at the correct width, it’s easy to keep it that way if you have the right tool. I use a zero-centered measuring tape which is, in my opinion, the slickest thing since eyelash curlers. Here’s how you use it; lay the measuring tape out on top of your machine’s belly bar, carefully placing the zero center of the measuring tape at the center point of the belly bar. This part is important, so take the time to make sure that the zero is in the right spot. Pin the tape in place at the zero so that it cannot shift. Working your way from the center to one end of the belly bar, smooth the tape out so that it lies nice and flat on the bar. When you get to the end of the machine, take note of which number on the tape is sitting on the very edge of your machine’s frame. Remove the tape from the belly bar.


Next, you will need to attach the tape to your machine’s frame. As you can see in Photo B I have stitched a short piece of Velcro (the soft part) on the underside of my tape and I stick that soft Velcro in place on the sticky Velcro that attaches my machine’s clamp straps to the end of the machine. When sticking the tape in place, make sure that you position it so that the number that was sitting on the edge of the frame in Step One is sitting on the edge now, thus ensuring that the zero center of the tape remains lined up with the center of your frame. Firmly press the Velcro in place so that it does not shift.


Okay, so now you’ve got a measuring tape stuck on the end of your machine’s frame. What next? Here comes the cool part; the tape that I use (Colonial brand ‘Longarm Centering Tape’) comes with twelve little sliding tabs that can be used to mark the correct measurements for any number of things on your quilt. In Photo C you can see that I am using a sliding tab to show me where the edges of my side borders should lay. (there’s a second tab at the 32 ½ point on the other side of the zero center to show me where the quilt’s left edge should be) I can also use the tabs to mark exactly where I want sashing strips to lay, or where I want a central seam line to hit, or where I want certain elements of blocks to be positioned. With each new advance of the quilt, I lay the measuring tape across the quilt top, making sure that everything that needs to be lined up is lined up and then I begin to quilt, knowing that everything is right where it should be. Easy peasy pie!

  1. Thank you so very much for sharing this info with me. I am a new quilter and this sounds like a great fix should I ever have an hour glass quilt. Diana
