Unless you are making something really small that takes only one ball of yarn, sooner or later you will need to join on some new yarn. And if you’re using more than one colour of yarn in a project, you’ll need to join on the new colour when you get to it.
If you are knitting and you can see you are close to the end of your ball of yarn, then it’s time to join in the new yarn. A join in the middle of a row can be visible so it’s better to change the yarn at the beginning of a row. To judge whether you have enough yarn to finish a row, measure the width of your knitting and then measure the length of your end of yarn. You need a length about three times the width of the knitting to get to the end of a row, so if you’ve not got enough, join on the new yarn. For a step-by-step guide to the technique needed see the know-how pages in Issue 8 of your Knit & Stitch Creative collection. You can use the same technique to change colour when making something striped – just like the Colourblock Sweater in the same issue.
When you want to join on a new yarn in crochet then – unsurprisingly – you use a different technique. To create a smooth transition from one yarn to the next, you need to use the new yarn to complete the last stitch made in the old yarn – and this is particularly important when changing to a new colour of yarn. To help secure the new yarn as you work and to prevent it slipping out, you can use a temporary knot. For a guide to how to join on yarn in crochet go to the know-how pages in Issue 8 of your Knit & Stitch Creative collection.
In both knitting and crochet you will need to weave in the yarn ends when you finish your project to ensure a neat finish.
