Jim’s Mystery Sweater is 13″ long now, which is long enough that I’m beginning to worry about whether or not I should start shaping steeks, and/or dividing for sleeves. While knitting, I decided that I would add gussets to provide a bit of room under the armpits. Adding these a big more complicated than a drop sleeve sweater, but not much.
I’ll be writing a calculator for this after I finish it. Meanwhile, I’ll explain how I do calculations as I go. Today’s main goal is to figure out when to stop knitting around and around without shaping and start increasing for gussets. To do this, I need to visualize the sweater, and figure out where the gussets start.
To illustrate the idea of what I’m doing, I snapped a photo of one of Jim’s old drop sleeve sweater. (I can’t use the one I’m making to illustrate because it’s just a tube!)
I’ve added a little triangle to represent the gussets I’m going to knit into Jim’s sweater. These gussets are just little diamonds of fabric created by increasing stiches every other row just before the underarm; I work them on the body and on the sleeves.
I need to start working these increases the length is shown with the blue line labeled “B” to the left. When I knit this sweater, I knit circular without shaping until I reach that length. After that, I increase 2 stitches under each underarm, every other row until I have “enough” underarm stitches. At that point, I want the sweater length to measure “C” as shown in the photo.
How do I figure out lengths “B” and “C”?
Well, if you look at the photo, you can see I need to know a) the final length I want for the sweater, b) how much shoulder shaping I plan to do, plus half the width of the top of the sleeve.
So, here are some values:
- Final length of the sweater: Jim likes his sweaters 27″ long. This is shown using a vertical green line.
- Shoulder drop: When I shape to drop the shoulder, I will make the outside shoulder 1″ lower that the final lenght of the sweater. I’ve shown this drop with a white vertical line in the photo to the left.
- Sleeve Width: Not accounting for gusset stitches, I want the sleeves to be 40% as big around as the body of the sweater. If you recall, Jim’s sweater will have a 40″ wide chest. So, that means I want 16″ wide sleeves. That means when the sweater is laid down, the folded sleeve will be 8″ wide at the top
So, now I have enough information to figure out the two lengths. (Well, actually, I also need to know my stitch and row gauge. But we know that, right? I’m getting 5 stitches / inch and 8 rows/inch.)
Now, here goes:
- Find Length “C”: Subtract the sum of the “shoulder drop” and half sleeve width from the total length of the sweater. For me that’s 27″ - ( 1″ + 8″) = 19 inches. That’s how long the work should be when I divide to work the back. But, I need to start the steeks a bit below that.
- Find how many stitches we want under the armpits: I want to have 5% of the total body stitches. If your recall, to knit the body, I cast on 200 stitches (that’s equal to 40 inches * 5 st/inch). So, I want 5% 0f 200 stitches = 10 stitches under eacharmpit.
- Figure out how many rows that’s going to take: I will be increasing 2 stitches at each underarm every other row. So, to increase 10 stitches will require 10 rows. (That was easy!)
- Figure out how much length those 10 rows use up: Divide 10 rows by my row gauge: (10 rows) / (8 rows/ inch) = 1. 25 inches. This is the length added by the gusset increases.
- Subtract that length from Length “C” to get Length “B”. Length B = 19″ - 1. 25″ = 17.75 inches.
Ok, I now know how long the work needs to be before I start working the gussets.
Directions for Jim’s sweater so far
- With smaller diameter needles, cast on 180 stitches. Join, being careful not to twist. Working circular, knit 1 x 1 ribbing until the ribbing measures 2 1/2 inches.
- Change to larger diameter needles. On next round, begin to work fancy stitch pattern, and also increase 20 stitches evenly — 200 stitches.
- Place a stitch marker at the beginning of the round; work circular until body measures 17.75″ but stop knitting one stitch before stitch marker. (Note: if you are working a fancy stitch pattern, you will need to center the pattern to look attractive. )
- Shift the stitch marker here! (Sort of pretend this is the beginning of the round now. The purpose is to make following direction easier.)
- Round 1: Slip stitch marker: ** K1, M1, k3, M1, K1, place another stitch marker. Work 97 stitches in fancy stitch pattern. place marker. Repeat from *. (Note: M1 means “make 1– it’s an increase. You may increase however you like to obtain the effect you find prettiest.
- Round 2: ** Slip marker, k5, slip marker, repeat from *.
- Round 3: Slip marker, K1, M1, k3, M1, K1 slip marker. Work 97 stitches in fancy stitch pattern.
- Round 4: ** Slip marker, k7, slip marker, repeat from *.
- Increase in pattern established until you have worked 10 rounds. (Note: you will have increased 10 stitches under each underarm.
- You will now divide the front, back and underarms. There are some options! I’ll let you know when I get further on Jim’s mystery sweater.
