How do you crochet knitted squares together for beginners?

How do you join knitting pieces together?

Using a third needle, knit the first stitch of the front piece together with the first stitch of the back piece. Work the second stitches of each piece together, then pass the first stitch on your needle over the second, as in an ordinary cast off. Repeat this fifth step until you have one loop left.

THIS IS FUN:  Your question: What happens if you use knitting needles that are too big?
