From Shirt to Pullover – close opening, check neckline
Changing from an open fronted design to a closed one looks as if it would be easy – just remove the button band. But there are some important things to check, to make sure you can get the garment on !

Removing the overlap
Removing an opening is fairly easy :
Assuming a front opening :
(If you’re starting from a pattern with a separate front band you’ll have to join the pattern pieces – overlap the seam allowances.)
Mark the centre front line (not the edge fold line) on the pattern (it should be printed on).
(I haven’t yet conquered high image quality, but hope the photos make the point.)
Trace the pattern to this line.
Fold the pattern on the line.
Add a note on the pattern, to remind you to place this edge on the fold of fabric.
Hey presto !
Though actually it’s essential to check the neck opening and underarm ease before cutting out.

Size of neckline opening :
Can you get your head through the resulting neckline neck opening ?
Measure your head. This is not your hat size, but your head measured loosely over hair, ears and nose. This is the size your neck opening needs to be for you to get it over your head. If you want to protect your hair-do or make-up, add an inch or two more.
On the front and back pattern pieces, draw in the neckline stitching line. This is easy to do with a French Curve which has 5/8 in. (1.5 cm) marked along the curved edge.
Measure the stitching line on the front and back patterns. Use the edge of a tape measure.
(back neck stitching line length + front neck stitching line length) times two
is the length of the neckline opening.
Compare this with your head size.
For example, on my fitting sloper, the back neck stitching line measures :
The front neck stitching line measures :
So half of neck line is :
3-1/8 + 4-5/8 = 7-3/4 in.
And the complete neckline length is :
7-3/4 x 2 = 15-1/2 in.
My head measures 25 inches (long hair up back of big head). So, if I want to use my fitting sloper as the basis for a pullover pattern, I need to make the neck opening much larger !

Changing the neckline
If the pattern neckline is not big enough for you, there are many things you can do.
To keep the same shape of neckline, lower the stitching line an 1/8 th. inch (3 mm) at a time, until the opening is big enough.
Or redraw the front neckline to a V or scoop neck, or widen the neckline at the shoulders to a boat neck. Or don’t close the opening completely but leave a neckline slit. Or transfer the neckline from another pattern. (So much to say on this I’m thinking of another post !)

Whatever neckline finishing treatment you use, make sure to lengthen it to match the new neckline.
Making a facing pattern :
It’s easy to make your own facing patterns. Draw a line 2 – 3 inches (5 – 7.5 cm) from the stitching line. That is the outer edge cutting line of your facing pattern.
If narrow facings flip out for you, use the 3 in. / 7.5 cm width. For me, this happens with wider necklines.
Lengthening a collar
If the pattern has a collar, you’ll have to alter that to match the new neckline.
Measure the neck stitching line from Centre Back to collar attachment point on the front.
Measure this on the original pattern and on your changed one.
Calculate the difference between the two.
This is the amount you need to change your collar.
On a straight collar, add it at the centre back.
These collar templates have a choice of lengths marked at centre back.
With a curved collar, mark the position of the shoulder seam. Then slash and spread, or slide, by the amount needed. You probably need to spread more at the outer edge of a curved collar, so it will lie in the same way as the original.
If you want to test your new collar pattern before cutting fabric, cut it out in kitchen roll paper. This has much the same firmness as interfaced fabric. (Sorry I can’t remember who I got this tip from.)

The final question about turning a pattern with an opening into a pullover top is – can you get it on over your shoulders ? I’ve got so much to say I made it a separate post.Explore posts in the same categories: pattern making for clothes
