SQUARE IT UP
QI am new to your magazine (and knitting as a hobby too). I am enjoying them both by the way! I know that it is important to knit a tension square for every project, but could you explain why in a bit more detail, as I am tempted to skip this step sometimes. Alexia Widicombe, via email
Yes, we all know we should knit up a small test square! But, let’s be honest: hands up those who have been guilty at one time or another of skipping this step, in our eagerness to cast on our project? It’s worth reminding ourselves why a tension square is so important, and how to get accurate measurements. For the best results from your knitting, you need to make sure you have the correct tension as this determines whether your garment will be a good fit.
How to make a square
Use the yarn and size of knitting needles that the pattern states. Most often, the instructions given will be for a 10x10cm square, but to correctly measure your tension, we recommend that you make a square at least 15x15cm in size. When you’ve completed the square, pin it to a padded surface (we used a firm cushion in our photograph), or a foam blocking mat. Gently smooth out your swatch, being careful that you don’t distort the stitches.
How to work out the tension
Use a pin as a marker and insert it vertically between two stitches. Then, using a rigid ruler, horizontally measure 10cm and place another pin in the fabric. Count the number of stitches between the two pins – be sure to include partial stitches. If your tension corresponds with that given in the pattern, you can start knitting your project. However, if you have more stitches than is stated in the pattern’s tension guide, it means that your knitting is too tight; try making another square knitted on needles that are one size bigger. If you have fewer stitches than is stated in the pattern’s tension guide, then your tension is too loose, so try knitting another square on smaller needles. Continue increasing and decreasing needle sizes until you get as close as possible to the tension stated in the pattern.
How to check row tension
Insert a pin horizontally and measure 10cm vertically and insert another pin. Count the rows between pins to see if they correspond with the pattern. If there are more or fewer rows, use smaller or larger needles to create another square. If the row tension is only slightly out (half a row to one row), it shouldn’t make much difference to the final garment, as most patterns instruct you to knit the piece to a certain length.
For best results, wash your swatch before you go ahead, and check the measurements again. If they’ve changed – swatch and wash again on larger or smaller needles. It may seem tedious, but it’s worth it for a garment that fits properly! Rachael
