How to Make DIY Sock Blockers

Spring is here – and that means it’s time to bring out the tiny needles and get working on smaller, lighter projects. Socks are a great year-round knit when you don’t want the warmth of a large winter jumper on your lap. However, for socks to look their best they really need a good block on a pair of sock blockers. This is where my plan to make DIY sock blockers began – I had a pair of beautiful socks fresh off the needles, but nothing to block them with to remove bunching and give them that classic ‘sock shape’. These sock blockers are created in 7 easy steps and are made out of things you probably have around the house: a cardboard box and tape!

Tools and Notions:

  • A flattened cardboard box (I used an Amazon box)
  • Two pieces of card or thick paper
  • A pen or pencil
  • A ruler
  • Cellotape (or other waterproof tape)
  • Scissors
  • Optional: A craft knife

Instructions:

Step 1) Place your foot onto a piece of card or paper. Position your foot in the centre and trace around it with your pencil.

Step 2) Next, you want to measure the widest and longest parts of your foot tracing. These measurements will inform the size of your cardboard blockers. For clarity, we will call the measurements of width (A) and length (B).

Step 3) Using your measurements (A) and (B), draw your sock blocker shape onto your other piece of card to create a template. I drew mine freehand with images of store-bought sock blockers as reference. *Remember that the width of the foot needs to match the (A) measurement and foot length should be equivalent to (B). See the image below for an example of this.

OPTIONAL: Try your sock onto your cut template. This gives you a chance to make any minor adjustments to the fit and shape.

Step 4) Using your card template, trace the sock blocker shape twice (or four times for double thickness) onto your flattened cardboard boxes.

Step 5) Cut out your blocker shapes using your scissors or craft knife.

Step 6) To ensure that the cardboard doesn’t disintegrate when it comes into contact with freshly washed socks, you now need to completely cover each blocker with tape.

Step 7) Now your blockers are watertight, they are ready for your next pair of washed socks!

As you can see, these DIY sock blockers do a fantastic job! The fit and appearance of this pair was massively improved by this simple, effective make. If you’re interested, you can read the whole review of this pair of socks here! The best part is that because I made these blockers to fit my feet, they should be perfect for every other pair I knit in the future.

I love my Into the Woods socks post-block. Using my DIY blockers is so satisfying, I might have to start knitting another pair of socks! Are you making any hand-knit socks for spring? Do you have a pair of fancy sock blockers or are you going to try to make your own?
