Making crocheted squares has a lot to do with making a perfect row. When you turn and begin a new row, you need to be sure you are chaining and starting in the right stitch to get an even and straight pattern. Once that has been mastered, the pattern can be repeated until the number of rows reach the same measurement as your beginning row width. The size of the square is determined by the yarn, hook size and beginning chain. The following are two basic pattern examples to practice a crocheted square.
Single-Stitch Crocheted Square
Chain 21 for the width of the square.
Single crochet in the first chain from the hook. Do not crochet in the chain the hook is in. Single crochet in each chain across for a total of 20 single crochet.
Chain 1, turn and single crochet in the first single crochet and in each single crochet across for a total of 20 single crochet.
Continue step 3 until the length measures the same as the width, creating a perfect crocheted square.
Shell-Stitch Crocheted Square
Chain 27 for the width of the square.
2 double crochet in the fourth chain from the hook. The first 3 chains become the first double crochet for a total of 3 double crochets.
Skip the next 2 chains. Double crochet in the next 2 chain. Skip the next 2 chains. 2 double crochet in each of the next 2 chains, creating a shell. Repeat from the beginning of step 3, ending with a shell in the last chain. Turn.
Chain 3, skip the next 2 stitches and make a shell in the next 2 stitches. Skip the next 2 stitches. Double crochet in the next 2 stitches. Repeat the pattern of step 4, ending with a double crochet in the last stitch. Turn.
Chain 3, 2 double crochet in the same stitch. Skip the next 2 stitches. Double crochet in the next 2 stitches. Skip the next 2 stitches. Make a shell in the next 2 stitches. Repeat the pattern of step 5, ending with a shell in the last stitch. Turn.
Repeat steps 4 and 5 until the length measurement equals the width measurement, creating a perfect crocheted square. Finish off.
To determine a starting chain for the basic shell pattern, chain in multiples of eight with three additional chains. This will allow you to keep the basic shell pattern and create the width you would like. Changing your hook size or your yarn type in the middle of a project will result in uneven sides and a distorted gauge.
