As happens every summer, I am once again sewing DARTLESS knit tops. I am once again trying to create the perfect dartless pattern, which will create the perfect dartless top. Again.

This one is very similar to a pattern I created a few years ago which pretty closely duplicates a Coldwater Creek short-sleeved knit top.

Basically, the pattern's front shoulder point is dropped severely, as if the side bust dart was scooted upward and removed at the shoulder! Of course, that is NOT what I did. No, I spent hours (days? weeks? years?) figuring out which numbers to change so that the program would create this shape for me!

The RED pattern (below) is the pattern for the above top. The blue/green patterns are my basic block, using similar drafting choices as were used for this one...for example, with the bust dart in the front armhole. You can see how the RED pattern has a very dropped front shoulder, yet the back shoulder remains unchanged. To prevent that front armhole from being WAY too small, I used the DART OVERRIDE tool to put some of the bust dart into the front armhole. As you can see, there is not much change in the sleeve, which means there is not much difference in the armhole lengths between these two patterns.

Below, the same two patterns are aligned at the hem/waist. As you can see, the front pattern is shorter on the RED one than on the basic block...this is because I reduced the CENTER FRONT LENGTH measurement to account for the stretch of the fabric.

I know that the front of my body will stretch the knit fabric more than the back of my body, so I can get more length from a knit fabric than I would get from the same cut-length of a woven fabric. So I can reduce the length of the front pattern to start with.
Also, as mentioned before, to lower that front shoulder point I reduced the FRONT SHOULDER SLOPE MEASUREMENT even more than I reduced the CFL...to increase the angle of the front shoulder. This is to prevent 'sagging' of the knit on the side of my body.
But as you may have noticed, this pattern is NOT dartless. There is a little dart there in the front armhole. Yet, I want a DARTLESS pattern! So the rest of the patternmaking was done in the PATTERN EDITOR.
I simply extended the dart to the CF line then rotated out HALF of the dart width. Then I drew a new CF line to connect neck and hem. The remaining dart will be eased to the sleeve...or ignored! This dart-rotation DOES remove a little width from the front pattern at bust level. And if you look back up at the top two pattern images, you might notice that the RED pattern is narrower at bust level than the basic block to start with! That is because I also reduced the BUST CIRCUMFERENCE measurement by 1.5". As it turns out, that was too much, especially when combined with this alteration which also reduces the width at bust level. But the top is wearable, even if the fabric is not gorgeous.

Speaking of not-gorgeous fabric, I am thinking I will over-dye this, and maybe print/paint on it, too. I mean, really, with my brown hair turning grey, I really don't need to wear a little black and white print that kinda reads as grey! Actually, this is not as bad on me as some shades of brown are these days!

This method DOES create a wearable dartless knit top and, as I said, it is VERY similar to the size, shape and fit of Coldwater Creek's knit top (size L). But it DOES ride backward some (just like the CWC tops) and I would like to eliminate that phenomenon.
I have created and sewn another knit top since this one, and I changed the way I treated the shoulder angles...stay tuned!
