To start a knitting project, you need to cast on stitches onto your needle. While there are many ways to do this, the Long-Tail Cast-On (also known as the continental or double cast-on) is by far the most popular. It creates an elastic, neat, and sturdy edge that works for almost any project.
Step-by-Step: The Long-Tail Cast-On
Before you begin, make sure you leave a long enough tail. A good rule of thumb is to measure about 3 times the width of the project you want to knit (or about 2-3 cm per stitch), plus an extra 15-20 cm for weaving in.
Step 1: The Slip Knot
Make a slip knot and place it on the needle. This counts as your first cast-on stitch. Hold the needle in your right hand.
Step 2: The Slingshot Position
Position the yarn in your left hand. The tail end should go over your thumb, and the ball end should go over your index finger. Secure both strands in your palm with your remaining three fingers. It should look like a slingshot.
Step 3: Go Under the Thumb Loop
Bring the needle tip down, then insert it up through the loop on your thumb from the bottom.
Step 4: Grab the Yarn
Reach the needle tip over to the index finger, grab the yarn strand going over it from the top, and pull it down through the loop on your thumb.
Step 5: Tighten the Stitch
Drop the loop off your thumb. Use your thumb to catch the tail strand again, and pull your thumb and index finger apart to snug the stitch onto the needle. Do not pull it too tight!
How to Avoid a Tight Cast-On Edge
A common issue for beginners is a tight cast-on edge that makes the cuff of a sleeve or sock impossible to stretch, or causes the edge to roll. To prevent this, try these simple tips:
- Cast on holding two needles: Hold two needles together as if they were one, cast on, then slip one needle out before starting to knit.
- Use a larger needle size: Cast on using a needle that is 0.5 mm or 1.0 mm larger than the one required for the project, then switch to the correct size for the first row.
- Leave space between stitches: Ensure there is a small gap (about 1-2 mm) between each stitch on the needle as you cast them on, rather than squeezing them tightly together.
