I love this modular technique of joining narrow strips of garter stitch together to create a larger piece. I first used it in the Jamie sweater and have returned to it time and again in some of my blanket designs (Evening Mesa Blanket, Flash Forward, Joinery).
The method of working the join is the same whether you’re working on the bias or a straight piece of knitting. The following tutorials combine the instructions for making right or left-leaning modular strips (worked on the bias) with the joining technique.
How To Make a Right-Leaning Modular Strip
Beginning on a RS row, knit into the front and back of the first stitch.
You’ve increased one stitch, which allows the strip to lean to the right.
Knit across the row until there are 3 stitches remaining.
Knit the next 2 stitches together. This decrease, along with the increase at the beginning of the row, is what allows the strip to lean to the right.
Yarn forward between the knitting needles so it’s at the front.
Slip the next stitch as if to purl.
Insert the right needle through the selvedge stitch of the adjoining strip from back to front, wrap the yarn around the needle as if purling and pull the stitch out through the back of the selvedge stitch.
This is basically a “pick up and purl” maneuver (similar to pick up and knit).
Pass the slipped stitch over the last stitch on the needle.
The RS row is complete.
With the wrong side facing …
slip the first stitch as if to knit.
Knit across the row until there’s one stitch left. Yarn forward.
Slip the last stitch purlwise.
Repeat those two rows (Steps 1 to 9) for the right-leaning modular strip.

To work a left-leaning modular strip, begin the RS row with k1, k2tog instead of the increase and work the KFB (knit into the front and back) increase in the second last stitch of the RS row instead of a decrease.
Jamie uses the same joining technique except there’s no shaping at the beginning and end of the RS rows. The whole sweater is assembled modularly with no sewing!
