How to Change Yarn Colors in Crochet

You can start working with new yarn at any place, but it's better to make it at the end of the row.

For working with a new color of yarn, you need to crochet until there are 2 stitches left on the crochet hook. Then, take the old yarn and the "tail" (leave 15 cm to hide) of the new yarn with 3 fingers of your right hand, which hold the crochet hook.

Then, you need to make 2 more stitches, pulling the threads that are left at the place when you insert the new yarn. You can make a temporary sailor's knot, and when your work is finished, turn and crochet these stitches to hide.
