Measurement C is measured horizontally across the front of the torso with the arms hanging completely relaxed. Measure from the very top of the torso/arm crease (yellow diamond in image) to exactly the same spot on the other side of the torso with the measuring tape against the body from point to point. This point is above the armpit. Make sure to measure from/to the very start of these creases. This location is Point C and is used for three measurements.
Measurement D is done exactly the same as Measurement C on the back. Point D, top of the torso/arm crease on the back, is used for three measurements. Once everyone’s done the test knit and we compare notes, we may reduce this point to “used for two measurements” as I think one of the measurements might be redundant.
Measurement E is measured vertically from Point B to Point C and is the depth of the positive armhole shaping in the front.
Measurement F is from Point B to Point D and is the depth of the positive armhole shaping in the back.
Measure G is from Point C to Point D around the upper arm. Start at the top of the front arm/torso crease, circle the outside of the arm and end at the top of the back arm/torso crease.
Measure H is from Point B to the armpit and is the depth of the armhole. The measuring tape should start on Point B and curve over the body and straight down to the depth of the armhole. Make sure to include the amount of ease you prefer in this measurement.
Measurement I is how much ease you prefer. This is where you set loose or tight. It won’t be used until you decide to use this technique to make a sweater. Ease is added after the work reaches the row count to reach Point C, calculation #6 in the spreadsheet unless you have generous front end real estate and need to start increasing sooner.
The measurements can be centimeters or inches with fractions, the spreadsheet should work either way. If it doesn’t, ping me and we’ll make adjustments.
Once you have all your measurements, it’s time to knit the sampler and/or knit a test fit using the spreadsheet.
