How to cast on purlwise with the longtail cast on. A step by step tutorial with close-up pictures and a video.
Have you ever looked very closely at your longtail cast on? It’s a great cast on technique, but if you look very closely at the first row of stitches you are creating, then they appear like knit stitches. The problem: When you turn the needles around to knit your first row, these will appear like purl stitches. So, when you knit across, you will be creating a garter stitch edge.
This can be nice because it prevents curling in stockinette stitch (a bit at least), but it doesn’t look as neat. And when it comes to ribbings, it suddenly not as perfect anymore. In this tutorial, I am going to show you how to do the longtail cast on purlwise.
When you alternate this new technique with the standard way, you get the basis for the perfect ribbings.
How to cast on purl stitches
To prepare, you need to set aside a little tail. I wrote a bit more about how much yarn you need for a long tail cast on here. As a rule of thumb, you can guestimate it 4 times as much yarn as your work will be wide.
The working yarn connecting to the ball should be on your left and the tail on your right.
Step 1: Wrap the working yarn around your pinky finger, bring it across the back of your hand, bring it under your stretched thumb and wrap it around clockwise once creating a nice loop here. I describe this in greater detail on my cast on tutorial for beginners. The extra length of yarn/tail should be on your left exiting your hand from the thumb.
Step 2: Create a slip knot.
Step 3: Bring your needles/yarn into the “slingshot” position.
Step 4: Insert the needle into the loop around your index finger from above and behind.
Step 5: Insert the needle into the loop around your thumb from below.
Step 6: Grab the yarn and pull it through the loop around your index finger.
Step 7: Remove your index finger from the loop and tighten up.
Repeat steps 3-6 until you got the desired amount of stitches on your needle. Combine it with the standard cast on as needed to alternate knit and purl cast-on stitches.
Important:What kind of cast on stitch your pattern requires, also depends on if you are knitting flat or in the round. Remember, when you are knitting flat, you are turning the project around. So, for a knit stitch in the first row, you will need to cast on a purl stitch and vice versa. For knitting in the round, this is not needed.
Also, here’s one more important thing to consider. If you are knitting stockinette stitch, by that logic, you would have to actually cast on purlwise to get an edge that reflects the pattern. In reality, you can also use the standard long-tail cast on and start with a purl row. This would mean you start on the “wrong side”, which you will ignore after that initial row.
This obviously doesn’t really work for knitting in the round. But here you only need to cast on purlwise if you need purl stitches.
