Judy’s Magic Cast-on

Judy’s Magic Cast-On (JMCO) is a revolutionary, invisible and seamless cast-on method, ideal for starting toe-up socks, top-down mittens, and other projects requiring a closed, tubular start. Invented by Judy Becker, this technique eliminates the need for a provisional cast-on and creates a beautifully smooth foundation.

In this tutorial, we’ll walk you through the step-by-step process of executing Judy’s Magic Cast-On, discuss its advantages, troubleshoot common mistakes, and explore the best ways to incorporate it into your knitting projects.

What is Judy’s Magic Cast-On?

Judy’s Magic Cast-On is a double-sided, invisible cast-on method designed to create a seamless edge. It works exceptionally well for projects that start with two joined edges, such as toe-up socks, bags, and even seamless toys.

How Does It Compare to Other Cast-On Methods?

• Figure 8 Cast-On: JMCO is neater and provides a more even tension.
• Turkish Cast-On: Both are seamless, but JMCO gives a more structured foundation.

Why Use Judy’s Magic Cast-On?

Here are a few reasons why Judy’s Magic Cast-On is a favorite among knitters:

• Invisible & Seamless – Creates a smooth, gap-free start.
• No Need to Pick Up Stitches – Unlike provisional cast-ons, stitches are ready to go.
• Perfect for Toe-Up Socks – Provides a symmetrical and professional finish.
• Versatile – Great for mittens, pouches, bags, and seamless plushies.

Materials Needed

To practice Judy’s Magic Cast-On, gather the following:

• Circular needles (Magic Loop method recommended) or double-pointed needles
• Yarn (smooth, worsted-weight yarn is ideal for practice)
• Scissors
• Tapestry needle (for weaving in ends when finished)

Step-by-Step Directions for Judy’s Magic Cast-on

Step 1: Hold the two needles together with your right hand, tips pointing left.

Step 2: Loop the yarn around the top needle, with the tail sandwiched between the top needle and the bottom needle and coming out the back. The Tail should have approximately 0.75″ / 2 cm for each stitch you’re casting on. The working yarn will go over the top.

Step 3: Pick up the yarns with your left and in the slingshot position, with the tail over your index finger and the working yarn over your thumb. This twists the yarns and creates a loop on the top needle that counts as the first stitch.

Step 4: While holding the stitch in place with a finger on your right hand, rotate the pair of needles up and wrap the yarn on your figure around the bottom needle, as if making a yarn over. Gently tighten the loop.

Step 5: Rotate the pair of needles downward and wrap the thumb yarn around the top needles as if making a yarn over. Gently tighten the loop.

Continue working Steps 4 and 5 to cast on the desired number or stitches. Alternate between top and bottom needles, with thumb yarn wrapping around the top needle and finger yarn wrapping around the bottom needle. End with Step 4, then proceed as follows;

Step 6: Turn the needles so that the bottom one is on top and the yarn ends on the right. Drop the tail and bring the working yarn up behind the top needle. Make sure the tail lies under the working yarn, between it and the needle. This twists the yarns so you can knit the first stitch. Knit across the first needle. The first stitch may become a little loose; just pull on the tail to tighten it.

Step 7: Turn the needles at the end of the first needle and knit the second needle through the back loop.

Common Mistakes & How to Fix Them

1. Uneven Tension

• Practice wrapping the yarn consistently around the needles.
• Avoid pulling too tightly, especially on the first few stitches.

2. Twisted Stitches

• Ensure that stitches lie flat and are not twisted before knitting the first row.

3. Gaps Between Stitches

• Keep the tension even when switching from one needle to the next.
• Knit the first few rounds snugly to close any gaps.

Advanced Tips for a Perfect Judy’s Magic Cast-On

• Use a larger needle size for the cast-on row if your stitches tend to be too tight.
• If using Magic Loop, ensure the stitches stay evenly distributed between the two needle tips.
• For a more seamless look, twist the first stitch before knitting into it.
