Super Sporty? Or An Evening Sweater? Sirdar’s 1930s Knitted Navy Pullover

This sweater is part of the re-issued collection that the yarn and pattern company Sirdar is offering as part of their Heritage Collection. These patterns are copied just as they are from old pattern books, so they have vintage sizing and vintage yarn. Sirdar offers some tips from using them, and I would suggest two things to do especially.

First, since a schematic or sketch of the shape of the pieces making up the garment is almost never offered in vintage knitting patterns, work one out by checking on the original gauge and multiplying as need by and taking a pencil to sketch it. Do this, so that you can figure out what size you will be. Vintage sizing is so different that I am a size 18 in 1930s sewing patterns and a 14 in today’s sewing patterns.

Second, create a gauge swatch and decide if you like the knitted fabric that results. Vintage garments were almost always made in what today we call fingering or sock weight yarn. That means they looked finer and often more sophisticated than our garments today, which are often made of worsted weight or bulky eight yarn, and they also take more time and effort. Once you have a schematic, you can recalculate the stitches and rows per inch if you want to change the size of the yarn, recognizing the final effect will be a bit different.  

I picked this sweater because of the interesting collar and cuffs with their large buttons with v-shaped openings which echo one another. Otherwise, this is a simple enough V-neck pullover with some vertical ribbing which creates a slender silhouette. The choice of navy yarn indicates the original designer thoughts of this as daywear, and knits were then thought of as sportswear and essentially informal public clothing. But with the right large buttons, color, and yarn, I see this as an evening sweater and one that could keep you warm while looking glamorous on cold nights.

Taking blood type data from the UK (source: Wikipedia whose source is the NHS) the population percentage and compatiblility are:

O+: prevalence: 35%. compatible with: O+ O-

O-: prevalence: 13%. compatible with: O-

A+: prevalence: 30%. compatible with: A+ A- O+ O-

A-: prevalence: 8%. compatible with: A- O-

B+: prevalence: 8%. compatible with: B+ B- O+ O-

B-: prevalence: 2%. compatible with: B- O-

AB+: prevalence: 2%. compatible with: A+ A- B+ B- O+ O- AB+ AB-

AB-: prevalence: 1%. compatible with: A- B- O- AB-

So we need to add up all combinations of Lucy's chances of having a particular blood type multiplied by the chance of Arthur having a particular compatible type. Doing this, we get the following data:

Lucy has O+ and Arthur is compatible: 16.8%

Lucy has O- and Arthur is compatible: 1.69%

Lucy has A+ and Arthur is compatible: 25.8%

Lucy has A- and Arthur is compatible: 1.68%

Lucy has B+ and Arthur is compatible: 4.64%

Lucy has B- and Arthur is compatible: 0.3%

Lucy has AB+ and Arthur is compatible: 2%

Lucy has AB- and Arthur is compatible: 0.24%

Inspired by Verse's excel spreadsheet, I also wanted to gauge a ratio between hits and kudos on my AA fics (mainly the Klapollo ones because the last two I posted got wayyyy more kudos than usual)

I don't have a spreadsheet sorry but I count my hits to kudos ratio as 10 : 1 because it's simpler on my not good at math brain. Using that ratio, damn! Why do those top two Klapollo fics have neary double the kudos to hits??

Percentage-wise, it's like. 19% and 17% vs 9%, 10%, 14%, 5%, 8%, 10%, 4%, and 6%. Less dramatic, but still a huge chunk of difference.
