The "Split Cowl Collar" Tutorial
First let's talk about the basic garment. The collar I'll be showing you can be added to any basic knit top. Here are some examples of patterns by Butterick and Vogue that would work with an added collar. Note that the necklines are either "crew" or "jewel" in general shape and depth..in other words..nicely rounded and not particularly deep or wide.
I am going to show you how I added a wide overlapped collar (what I call a ""Split Cowl") to an otherwise simple knit pullover top. The bodice and sleeves are made with Rayon knit Jersey purchased from www.GorgeousFabrics.com several months ago, and the collar is made from gray rayon ribbed knit that I have in my "fabric stash". ** Please note that all seam allowances used in this tutorial are 1/4-inch---if you start with a pattern that has 5/8" seam allowances, the neckline seam allowance needs to be trimmed to 1/4-inch **
Here are the bodice pieces shown side by side. The front neckline is about 5-6 inches deep. At the end of this tutorial you will see variations that have lower or higher necklines but the construction technique is the same.
The next step is to sew the shoulder seams--
Now the complete neck-edge (the "hole") needs to be measured. I've found that the easiest way to measure the length of curves is to stand the tape-measure up on its edge, and that is what is shown below-
Because the collar is going to be overlapped and so therefore "scientifically exact" measurements are Not needed, I am going to say that this neck edge is 21 inches around. A collar needs to be made that is 21-inches long, plus a generous 3 inches for overlap and to have enough to seam the ends. So the LENGTH of the over-lapped collar needed to fit this particular neckline is 24"...and I usually add an extra inch to give myself a little more overlap. Now what about the width? I have made so many of these tops over the years that I know that I like the results best when the cut collar width (flat and single thickness before it is sewn) is 8 inches to 12 inches wide. As you will see, this is an arbitrary width measurement, and after you make one, you will see the endless design possibilities by changing the width and shape of the collar.
So I have decided that for this top, my collar will be cut 25 inches LONG and 10 inches WIDE.
WAIT! Before we all go cross-eyed...let's pause a moment and put this into perspective-- Remember...this is an easy technique...you'll see! It boils down to this--A very basic rectangular collar is going to be stitched into "the neckline hole" that you see above. There, that's it in a nutshell! Now let's continue....
Normally I just go ahead and cut out my collar from the fashion fabric and stitch it in. However, you can make a "test" collar from scrap fabric (that you can use as a pattern later) to see if you've measured correctly and like the width and finished folded depth of your collar. Below is a piece of scrap fabric that has been cut to my determined 25- inch length and 10-inch width.
Then I quickly folded it in half lengthwise, and sewed the short ends with a 1/4-inch seam allowance--
Next I turned my "test" collar right sides out....and then overlapped it in preparation for it to be sewn to the neck-edge (the yellow pin you see is holding the overlapped collar at its raw edge....the folded edge of the collar is toward the bottom of the photo)--
The photo below should make things more clear. The bodice has been turned wrong side out, and the collar is going to be "dropped" inside of the neckline "hole", all the raw edges will be aligned, and the collar will be basted (by hand or by pins) to the neckline...right side of collar to right side of neckline.
Note that a yellow pin has been placed at the center back of the shirt and another at the center back of the collar. Then...when the collar is dropped down into the neckline "hole"...
To check the appearance of the test-collar, turn it right side out, as shown below--
I was satisfied with the appearance of the collar, and decided to use the same measurements for the "real" collar. If I had wanted to, I could have quickly taken the stitching out and used the test-collar as the pattern for the "real" collar, but I like to just measure and cut simple rectangle shapes with my ruler and rotary cutter, rather than scissors and a pattern. So I did so with grey ribbed knit The short ends of my ribbed collar were stitched and turned right sides out.....and then I hand basted the raw edges to prevent them from shifting before I stitched the collar into the neckline "hole".
In the photo below, the shirt is folded in half, matching the shoulder seams and the neck-edges. The collar is folded in half as well and compared against the neckline, as a guideline for how much to overlap the collar....and where to place the overlap (which is your choice..it can be placed wherever you want it to be).
The collar is stitched to the neckline with a 1/4-inch seam by sewing machine or serger. The seam can be left as is, however I like to finish the seam so that it lays flat by top-stitching it down from the right side, as shown below.
Below you see the finished collar and bodice from the right side--
As you look at the photograph above...are you wondering how a collar that is the same length on each short side, now looks like one edge is quite a bit longer and...that now, somehow, the collar is asymmetric? Here's why: The upper side of the overlap is exactly that...an OVER-lap.
Well...because is has to go up and OVER the other side-edge of the collar, it merely appears to be shorter! And because the under-lap does not have to do anything but lay there....it merely appears to be longer! I just love when a straight collar "auto-magically" becomes asymmetrical just because one side overlaps the other :)
Here are some variations of the design based on the same theme--
This version in Aqua stretch velour features a deeper U-shaped neckline, and the collar was cut about 8" wide with No overlap.
