Cuff-Down Socks Class: Heel Flap!

Step by Step 1/1 LslT RS (Left-slip-Twist) Knitting Tutorial


Today is our fourth day of the Beginner Sock Knitting Class for Cuff-Down Socks!

Every day for the next week I'll be sharing a tutorial filled with the how's and why's of constructing a sock from the cuff through the toes. At the end of this week-long class I'll provide you with the Basic Cuff-Down Sock pattern (with heel flap) that I've used when filming the lessons so that you can cast-on a set for yourself or a loved one.

If you were hoping to learn how to knit socks from the toes-up, I've got you covered. I'll be running another free sock class starting January 20th for my Basic Toe-Up Socks (with a short-row heel). Again, that class will walk through the construction and will be followed up with the release of the free pattern on January 27th, 2021.

Today we'll be learning:

  • Note: At the end of this video I mention that the Heel Turn will be in a separate video but the same lesson. As I was writing up this lesson I realized just how much content we covered in this video & will be doing a separate lesson for the Heel Turn tomorrow just to keep things nice and clear for everyone.

How to Measure the Leg

When measuring your sock to determine if you're ready to start your heel you will be measuring from the cast-on edge to where your needles currently are in the knitting.

Remember, always lay your sock flat on a hard surface. Using something like the couch or even your leg can stretch the fabric without you realizing and give you the wrong measurements. Exact measurements aren't as crucial in the leg section, but you're going to want accurate measurements when you are working on the foot later on so it's best to get into the habit now.

What is an Instep?

The instep is simply another word for the top of your foot between your ankle and toes. When we're working the Heel Flap and Heel Turn, the instep stitches are put on hold. They're picked up in the Gusset when we start working in the round again.

What is a Heel Flap?

A Heel Flap is a square (or rectangle) of fabric that we make to cover the back of the heel. It's worked flat and usually incorporates some kind of slipped-stitch pattern for stability or a stitch design to create an extra bit of beauty in an unexpected place.

Heel Flap Benefits:

  • Sturdiness - Because most heel flap patterns feature slipped stitches or other techniques to make a more dense fabric, Heel Flaps generally hold up better to wear and tear than other types of heels.

  • Customization - Since we're building the depth of the sock's heel when we make the heel flap, you can easily make it deeper or more shallow by adding or decreasing rows. This is especially helpful if you have high or low arches that can be difficult to accommodate normally.

What is a Selvedge Edge?

A Selvedge Edge is one or more stitches made consistently along the side of fabric that essentially creates a border. This will give the piece a finished look and makes it easier to pick-up stitches later on if needed.

In knitting a Heel Flap we are creating a 1 slipped stitch selvedge edge because we'll need to pick up those stitches later on when we begin working the Gusset. The slipped stitches are much easier to see and work into than a non-slipped edge.

How To Make a Basic Heel Flap

A Heel Flap is worked over 1/2 of the available stitches. It's a good idea to place markers at both the beginning of the round and at the 1/2 way point so that you can easily see which stitches to use in your Heel Flap.

Row 1: *Slip 1, knit 1; repeat from * to end of Heel Flap. Turn.

Row 2: Slip 1, purl across to end of Heel Flap. Turn.

Continue repeating Rows 1 & 2 until you have worked as many rows as you have stitches in your Heel Flap. (For example, I'm working my Heel Flap over 32 stitches so I'm working 32 rows.) You can work more or less rows depending on how deep or shallow you want your heel cup.

Remember, always slip your stitches as if to purl so that you don't twist them! (Unless your pattern tells you otherwise.)

That's it!

Next up, we'll work on the heel of the sock. I'll cover that in more detail in tomorrow's lesson. See you then!
