How to Knit & Crochet Squares

Updated April 17, 2017

Knit and crochet squares serve as the basis for numerous knit and crochet projects. Squares sewn together form afghans, shawls, pillow covers, rugs, bedspreads and many more projects. The most basic knit stitch is a garter stitch, which is made by knitting every row. The easiest crochet stitch is the single crochet stitch. Learning these two techniques will serve as the foundation for all other knitting and crochet stitches. Once you master these basic squares, you can get creative and branch out into other stitch types and patterns.

Make the cast on row. To do so, tie a slip knot roughly six inches from one end of the yarn. Place the knot on the knitting needle held in your left hand.

Insert the tip of the knitting needle in your right hand through the knot on the left needle, sliding the right needle behind the left needle.

Wrap the yarn over the right needle's tip from the back of the needle to the front of the needle. Use the yarn coming from the skein of yarn, not the yarn tail from the slip knot.

Pull the right needle through the knot; a new loop will be on the right needle. Slide this loop from the right needle onto the left needle.

Repeat this process until you have 18 stitches on the left needle, counting the slip knot.

Knit across all 18 stitches. To knit, act as if you were making a cast on stitch, but instead of transferring the new stitch from the right needle to the left, leave the stitch on the right needle, and drop the stitch you worked through off of the left needle.

Knit all rows until your work is four inches long from the beginning cast on row. This is garter stitch. You will have a 4-inch by 4-inch square.

Cut the yarn, leaving a 6-inch tail. Thread the yarn through the yarn needle and make a few stitches along the bottom row of knitting to hide the loose end. Cut any remaining yarn from the loose end. Hide the loose end from the slip knot in the same manner.

Create a foundation chain of 15 stitches. Place a slip knot on the crochet hook, holding it in your left hand. Wrap the yarn around the hook's tip from back to front, pulling the yarn from the skein.

Pull the hook through the slip knot, creating a new loop. This is one chain stitch. Repeat this process until you have 15 chain stitches, not counting the slip knot.

Make one single crochet stitch in the second chain stitch from the hook. Insert the hook into the second chain stitch from the hook. Wrap the yarn around the hook, and pull it through the stitch. Wrap the yarn around the hook once more, and pull it through both loops on the hook. This is one single crochet stitch.

Make one single crochet stitch in each chain stitch along the foundation chain. Make one chain stitch and turn the work so that the last stitch made is now facing as the next stitch to work.

Repeat Step 4 until the work measures 4 inches from the beginning. You will have a 4-inch by 4-inch square. Cut the yarn, leaving a 6-inch tail. Wrap the yarn around the hook and draw it through the last stitch on the hook. Sew in all loose ends as directed for the knitted square.
