Thread a yarn needle with about 2 yards of the yarn you'll be using for the project. Coil the clothesline as shown (actually, the coil should be tighter...I made it loose to better illustrate.) Insert the needle through both thicknesses of the clothesline.

Wrap the yarn tightly around the coil as shown to form a ring; tie to secure, then run the ends of the yarn under the wraps to hide.

Attach yarn to the hook with a slip knot. Beginning to the left of the uncoiled clothesline, work 8-10 sc around the ring to cover.

Insert hook into the first sc and under the uncoiled clothesline.

Complete sc. Do not join rounds; instead, use a stitch marker to mark the first sc of each round. (I'm using pink yarn for a marker.)

Working each sc into the indicated st and around the uncoiled clothesline, work 2 sc in each sc around.

Continue working sc in rounds, working around the clothesline and increasing each round (if you worked 8 sc in step 3, increase 8 stitches in every round. If you worked 10 sc in step 3, increase 10 stitches in every round) until the piece is the desired size.

Coaster size: 4" - 5"

Trivet size: 8" - 9"

Chair pad size: 14" - 15"

Placemat size: 16" - 18"

Rug size: 36" or more

Cut the clothesline, leaving 1" - 2" of unworked clothesline exposed. Fasten off yarn, and cut the yarn, leaving a  24" yarn tail. Thread the yarn needle with the yarn tail. Insert needle through the clothesline, near the last sc, and into the clothesline of the previous round. Repeat 2 or 3 times.

Cut clothesline close to the last stitch. Knot yarn in the back of the piece, then run yarn needle under coils to hide yarn end.
