Magic Circle

A crochet magic circle, also called a magic ring, is a technique used to start projects worked in the round, like hats or amigurumi. It creates a tightly closed center, unlike traditional chain starts, which can leave a small hole. By crocheting your first round of stitches into an adjustable loop, you can pull the tail to close the circle completely, giving your project a clean and professional look.

I have a very simple and easy tutorial on how to create a magic circle.

Invisible Join

1. Cut the working end of your yarn and pull it up and through the last stitch that was worked.

2. Thread the tail of yarn through a tapestry needle.

3. Skip the first stitch, insert your tapestry needle into the second stitch from front to back through both loops of the stitch, pull yarn through.

4. Insert your tapestry needle from front to back into the back loop only of the stitch the yarn is originating from, pull yarn through.

5. Securely weave in your ends.

I have full video tutorial and blog post on how to create an invisible join.
