This is one of my first crochet patterns that I designed. Orginally I sold the pattern, but now have decided to make it available for free. It is a granny square crochet pattern and provides instructions on how to join the squares in order to make a granny square afghan, hat, scarf and poncho.

These are great patterns for using up leftover yarn as different colors may be used for each square.

Material: 4 colors of Red Heart Comfort or any yarn you have on hand.
Hook Size: I/9-5.50MM, or one suitable for the yarn.
Gauge: Measures 1" across first round. Before joining, each square measures about 4.5" across.
Hat Measures: 8" from top to bottom when laying flat, and 22" in circumference.
Scarf Measures: 5.5" wide, and 67" long.
Poncho Measures: 16" across squares from neckline outward, and 24" diagonally across squares from point in neckline to bottom point. The size may be increased by adding another round of squares.

With color 'A' ch 4, join with sl st to first ch.

Rnd 1: Ch 1, work 2 sc in each ch. Join with sl st to first sc. (8 sc)

Rnd 2: Ch 1, sc in same st, ch 4, skip next st, (sc in next st, ch 4, skip next st) 3 times, join with sl st to first sc. (4 loops) Fasten off.

Rnd 3: Join color B into center of loop, ch 3, (counts as first dc), 2 dc in same loop, (3 dc, ch 2, 3dc) in next loop 3 times, (3 dc, ch 2) in beginning loop. Join with sl st. Fasten off.

Rnd 4: Join color C into loop, ch 3, (counts as first dc), 2 dc in same loop, dc in next 6 sts, *(3 dc, ch 2, 3 dc) in corner loop, dc in next 6 sts. Repeat from * twice, then (3 dc, ch 2) in beginning loop, join with sl st. Fasten off.

To join the squares for the afghan:

First Square: Join color 'D' to center of corner loop, ch 1, sc in loop, ch 2, sc in same loop, *sc in next 3 sts, (ch 2, sc in next 3 sts,) 3 times, sc into corner loop, (ch 2, sc,) twice in same corner loop.* Repeat from * to * another 2 times, then sc in next 3 sts, (ch 2, sc in next 3 sts,) 3 times, (sc, ch 2, sc) into first corner loop, join with sl st. Fasten off.

Note: Squares are joined with a sl st into each corresponding ch-2 loop along the side and at each corner. All joining sl sts are worked by inserting the hook from the wrong side of corresponding ch-2 loop of previous or completed square.

Joining One side of the Square:

Join color 'D' to center of corner loop, ch 1, sc in loop, *ch 2, sc in same loop, sc in next 3 sts, (ch 2, sc in next 3 sts,) 3 times, sc into corner loop, ch 2, sc in same loop.* Repeat from * to * another 2 times. To join ch 1, sl st into corresponding corner loop of first or completed square, ch 1, sc in same loop of current square, **sc in next 3 sts of current square, ch 1, sl st into corresponding ch-2 loop of first or completed square, ch 1. Repeat from ** another 2 times, then sc in next 3 sts of current square, sc into corner loop, ch 1, sl st into corresponding corner loop, ch 1, sc into corner loop of current square. Join with sl st into first sc. Fasten off.

Joining Two Sides of the Square:

Join color 'D' to center of corner loop, ch 1, sc in loop, *ch 2, sc in same loop, sc in next 3 sts, (ch 2, sc in next 3 sts,) 3 times, sc into corner loop, ch 2, sc in same loop.* Repeat from * to * once more. To join ***ch 1, sl st into corresponding corner loop of first or completed square, ch 1, sc in same loop of current square, **sc in next 3 sts of current square, ch 1, sl st into corresponding ch-2 loop of first or completed square, ch 1. Repeat from ** another 2 times, then sc in next 3 sts, sc into corner loop, ch 1, sl st into corresponding corner loop of first or completed square, ch 1, sc into corner loop of current square. Repeat from *** once. Join with sl st into first sc. Fasten off.

Joining Three Sides of the Square:

Join color 'D' to center of corner loop, ch 1, sc in loop, ch 2, sc in same loop, sc in next 3 sts, (ch 2, sc in next 3 sts,) 3 times, sc into corner loop, ch 2, sc in same loop. To join ***ch 1, sl st into corresponding corner loop of first or completed square, ch 1, sc in same loop of current square, **sc in next 3 sts of current square, ch 1, sl st into corresponding ch-2 loop of first or completed square, ch 1, repeat from ** another 2 times, then sc in next 3 sts, sc into corner loop, ch 1, sl st into corresponding corner loop of first or completed square, ch 1, sc into loop of current square. Repeat from *** twice. Join with sl st into first sc. Fasten off.

Note: When working on the edging you will notice there are 4 sc sts before and after each corner ch-2 loop; insert the hook and sc in either one of the center sts.

Edging:

Join color 'D' to any ch-2 loop along edge, ch 1, (sc, ch 3, sl st in third ch from hook, sc) all in the same loop, **work 1 sc in center of next sts between ch-2 loops, *(sc, ch 3, sl st in third ch from hook, sc) all in the next ch-2 loop, work 1 sc in center of next sts between ch-2 loops.* Repeat from * to * until you come to a corner. (sc, ch 3, sl st in third ch from hook, sc) in each of next 2 ch-2 loops. Repeat from ** until you have worked your way around back to the first sc, join with sl st. Fasten off.
