Knitting designer series:Â I invited a few of my favourite knitwear designers to discuss their design process and inspiration and to share some tips and ideas too.

After Iâ€™ve published a new pattern, I often talk about my inspiration for the design, but I only focus on what it looks like. Rarely, if ever, do I get down into the details of how the pattern itself comes about. In my fantasies, after I have an idea for a design and make a little sketch, I just sit down one day and knit the whole thing. But the truth is that there is a whole lot of planning and math that makes a design what it is. So I thought Iâ€™d tell the story of a pattern, my Indicum Pullover, from start to finish, and include all the gory details, whether glamorous or not (because seriously, math is not very glamorous). [Pictured above]
The idea for Indicum came from something I spotted on The SartorialistÂ some months ago. You couldnâ€™t see much of the womanâ€™s sweater (and I didnâ€™t even save the photo), but it looked like a big pink crewneck pullover with some orange peeking through the ribbing at the sleeve cuffs and hem â€“ and that orange ribbing really caught my eye. I jotted down â€œsimple stockinette pullover with corrugated ribbing at hemsâ€ in my planner then just couldnâ€™t get it out of my head.
Armed with inspiration and the seed of an idea, I got to work figuring out the details of the design â€“ what specifically did I want this thing to look like? Now, I am not exactly skilled in the area of drawing, so unless Iâ€™m making a fashion-y sketch for a design submission, I donâ€™t spend much time on this part. My sketches for self-published designs are more like schematics: two-dimensional representations of the finished piece, with construction notes and some measurements thrown in as well.
During this part of the process, I also spend some time standing in front of the mirror with a tape measure and a top with a similar fit to what Iâ€™m going for in my new design. I tug and measure, then tug and measure some more, noting at what depth I like the neckline best, and how long I want the sleeve to be (and, no, I will not be sharing a picture of this).
With Indicum, I immediately knew what yarn I wanted to use for the majority of the sweater. Iâ€™d had some lovely indigo-colored Malabrigo SockÂ in my stash just waiting for the right idea for a couple of years. To decide on the contrast color for the corrugated ribbing, I started sketching again, but this time in yarn.
The neon green Koigu KPM had more contrast than I wanted, and the ribbing with two colors was just a little too much. But I fell in love with the purple yarn alone. Itâ€™s Plucky Knitter Primo FingeringÂ and is just variegated/semi-solid enough that the purl bumps show up slightly differently in different rows. This was it.
Now, the math part of designing and pattern writing is something I always dread but end up having a great time doing. After the sketching and playing around with yarn, itâ€™s like a little workout for the other side of my brain. It also feels like solving a puzzle and is so gratifying when all the pieces fall into place.
The first step is to do a nice big swatch, wash it, block it, and get a good, accurate gauge (remember this).Â Next, I plug my gauge and my target measurements into a spreadsheet and start calculating stitches and rows for all the different sizes Iâ€™ll offer.Â Excel does the multiplication and addition, but I have to pay close attention to make sure I havenâ€™t entered any funny formulas or have any incorrect cell references. I alsoÂ reallyÂ have to pay attention to things like multiples of stitches (e.g. multiple of 3 for the ribbing, multiple of 2 for the bust, since I need to be able to divide it by 2) and that I donâ€™t have more decrease repeats than rows in which to do them, etc. The spreadsheet I use is based on one I downloaded from Marnie Macleanâ€™s fantastic tutorial on grading/sizing using ExcelÂ and Iâ€™ve adapted it over the past couple of years to suit my needs.
If my design has a feature (like Indicumâ€™s scoop neck created with short rows done at the same time as circular yoke shaping) that canâ€™t just be plugged into Excel, sketching can help me visualize how the math works out.
(Donâ€™t ask me what any of this means â€“ it ceases to make sense the minute I start thinking about something else.)
This is the part I really love. Unfortunately, this is also the part where I find out if my math is wrong, my sizing is funky, or, in the case of Indicum, that my gauge swatch totally lied to me. Now, occasionally the stars align and a sample turns out perfectly the first time and doesnâ€™t require any math adjusting or tinking back. But Indicumâ€¦ oh, Indicumâ€¦ I knit almost the entire sweater before realizing my gauge was off by a stitch (Gauge swatch? 22sts per 4â€. Reality? 21sts per 4â€. Just enough to make the sweater totally too big. UGH). So, the math was re-done, Indicum was ripped out, and I started knitting it a second time. But the second one worked out just like Iâ€™d planned. Yes!
The pattern-writing process could easily take up a book of its own, so Iâ€™ll stop here. But, suffice it to say, quite a bit goes into taking a design from a little spark of inspiration in your head to an actual knitted garment, and thereâ€™s nothing quite like seeing it all come together. I encourage everyone who is so inclined to give it a try. Just be sure to double-check your gauge.
