How to Do Judy's Magic Cast On for Toe-Up Socks

Judy's Magic Cast On starts toe-up socks with no gap and no seam. Here's how to work it step by step on two circulars or magic loop.

Quick answer: Judy's Magic Cast On casts stitches onto two needle tips simultaneously โ€” half on each โ€” creating a seamless, gap-free toe start for toe-up socks.

What it is

Judy's Magic Cast On (by Judy Becker) creates a seamless, gap-free start for toe-up socks or mittens. Stitches are cast onto two needles at once, ready to knit in the round immediately.

When to use it

  • Toe-up socks on two circulars or magic loop
  • Thumb-up mittens
  • Any small-circumference project starting from a closed tip

How to do it

  1. Hold two needle tips (or both cable ends of magic loop) parallel in right hand.
  2. Make a slip knot on the top needle โ€” first stitch.
  3. Hold tail over index finger, working yarn over thumb.
  4. Loop the tail yarn up and over the bottom needle. (1 stitch on bottom.)
  5. Loop the working yarn up and over the top needle. (2 stitches on top.)
  6. Alternate: loop tail over bottom, loop working yarn over top โ€” until you have equal stitches on each needle.
  7. Turn work so bottom needle is on top. Knit across. Turn again. Knit the other needle. You're knitting in rounds.

Common mistakes

  • Wrong yarn direction โ€” loops should all twist the same way
  • Unequal stitches on each needle โ€” cast on exactly the same amount on each
  • Slip knot too loose โ€” creates a hole at the very start
