This tutorial will help you to change color in single crochet. It is fairly easy, don't feel overwhelmed. I know it's easy to be frightened of trying something new but, just give it a go. With practice it becomes much easier and hopefully this little photo tutorial will help.
Single Crochet Color Change
Step 1- Chain any number of stitches, ( for this tutorial I chained 10) working in second chain from hook single crochet in all chains up to the last chain.
Step 2- In last chain single crochet but stop when you have two loops on your hook. Instead of yarning over you are going to place the new color on your hook.
Step 3- Pull new color through the two loops on your hook.
Step 4- Chain 1, single crochet in new color all along next row until the last stitch, repeat steps 2-4 to change color again. Ta-dah, you've done it! Now keep practicing and you will get better as you go.
Good Luck and Happy Hooking!
