Adding Elbow Patches:

Using a sharp darning needle, whip stitch the elbow patches into place.

Of course, you do not have to add the elbow patches, especially to the 12 month cardigan size. If you do, however, the cheapest I have found the patches is $3.99 per 2-pack. I cut one of the patches into two smaller sizes for this 12 month cardigan, and I’ll use the other patch cut into two for the 2/3t size when that is completed!

Should you have any questions, don’t hesitate to shoot me an email or a message, and I want to see your finished projects!! Share photos of your Cozy Classroom 12 Month Cardigan with me by tagging @HeartHookHome on Instagram and Twitter, and by sharing in the Heart Hook Home Crochet Community group on Facebook!

When all of the child’s sizes are completed, I will offer them as one download, similar to that of the Painted Canyon Cardigan. Woot!
