Designing my first jumper pattern using software design principles
Posted on June 18th, 2008
I have some Paton’s Inca in a beige blend (the same colour that the One Piece Jacket was done in) but I can’t find exactly the sort of pattern that I want to knit, so it’s time to design my first jumper. I’m an information systems major rather than a textiles major, so I decided to apply software engineering principles to designing my jumper.
So, first of all, requirements elicitation. The business requirements of the jumper are;
- The jumper must accentuate my “assets” while downplaying any not-so-desirable attributes
- The jumper must fit, and should have plenty of stretch
- The jumper should be easy to maintain
- The jumper’s cost should be less than $150
Translating the business requirements into functional requirements;
- The jumper will have a v-neck that is 2o cms deeper than the top of my shoulder and shaping will begin 8 cms in from the shoulder. The v-neck accentuates the bust while drawing attention away from the hips and gives room for movement
- The jumper will be knitted in 1 x 1 rib to give shaping and stretch
- The jumper will have slight increase to allow for large bust and decreases for waist, possible increase for hips
- The jumper will have sleeves that finish 10 cm below the elbow (my preferred sleeve length)
- Paton’s Inca is $6 at Lincraft or $5.40 at K-mart (unless I can twist Damo‘s arm to get ACS to offer bulk packs cheaper). Therefore, the pattern must take less than 26 balls of yarn if I buy them at K-mart.
