One Skein Scarf: An Easy Knit That Uses the Whole Ball

One skein is enough for a scarf if you let the yarn decide the dimensions. A fixed amount of yarn covers a fixed area of fabric, so every inch you add to the width is taken from the length. The method here is to read the yardage on the label, choose a width that leaves a wearable length, knit in garter stitch until the skein is almost gone, and stop with just enough left to bind off.

Read the Yardage, Not the Weight

Skeins are sold by weight, but scarves are made of length. Two 3.5 oz (100 g) skeins can hold very different amounts of yarn: a worsted-weight (#4) skein of that size often has around 200-220 yd (183-200 m), while a super bulky (#6) skein of the same weight may have under 100 yd (91 m). The yardage figure on the label is the one that tells you how big the scarf can be.

As a rough guide, a typical adult garter scarf of 7 x 65 in (18 x 165 cm) covers 455 square inches and takes about 250-350 yd (230-320 m) of worsted yarn, 180-250 yd (165-230 m) of bulky, or 120-180 yd (110-165 m) of super bulky. Dividing the area by the middle of each range gives a working figure for how much fabric one yard makes:

• Worsted (#4): about 1.5 square inches per yard
• Bulky (#5): about 2 square inches per yard
• Super bulky (#6): about 3 square inches per yard

These are estimates for garter stitch at an ordinary gauge. Tight knitting, ribbing and textured stitches all cover less. The guide on how much yarn a scarf needs goes through the ranges in more detail.

How Far One Skein Goes

Multiply the yardage by the figure above to get the area, then divide by the width to get the length. For a 220 yd worsted skein: 220 x 1.5 = 330 square inches, and 330 / 6 = 55 in.

The lengths are rounded and approximate. Expect to land within a few inches either side.

Pick the Width So the Length Works

Most adult scarves are 6-8 in (15-20 cm) wide and 60-70 in (150-180 cm) long. The table shows that a single skein rarely gives both at once, so decide which matters more.

• Length first: at 5 in (13 cm) wide, a 220 yd worsted skein reaches about 66 in (168 cm), a full-length narrow scarf.
• Width first: at 6 in (15 cm), the same skein gives about 55 in (140 cm), long enough to cross once under a coat collar.

The scarf width and length guide has the full ranges if you are knitting for a particular person.

The Pattern

This version uses one 220 yd (200 m) skein of worsted yarn on US 8 (5 mm) needles, at a gauge of about 4 stitches per inch in garter stitch. Abbreviations: CO (cast on), k (knit), sl (slip), st(s) (stitch or stitches), wyif (with yarn in front), BO (bind off).

1. CO 24 sts for a scarf 6 in (15 cm) wide (6 x 4 = 24), or CO 20 sts for 5 in (13 cm) wide (5 x 4 = 20). Leave a 6 in (15 cm) tail.
2. Every row: sl 1 purlwise wyif, move the yarn to the back between the needles, knit to the end. On 24 sts that is 1 slipped st and k23. On 20 sts it is 1 slipped st and k19.
3. Repeat that row until the yarn is nearly used up, following the stopping rule below.
4. BO all sts loosely. Cut the yarn and pull the tail through the last st.

If you would rather skip the slipped edge, simply knit every stitch of every row. The stitch count and the yarn used are the same. For the stitch itself and how to count its ridges, see the garter stitch scarf pattern.

Check the Length Before You Are Committed

A kitchen scale can confirm the estimate early. Weigh the full skein before you begin, knit 10 in (25 cm), then weigh the ball that is left.

Example: the skein weighs 100 g at the start and 82 g after 10 in. The scarf has used 100 – 82 = 18 g, which is 1.8 g per inch. The whole skein will therefore make about 100 / 1.8 = 55 in (140 cm). If that is shorter than you want, this is the moment to rip out and cast on fewer stitches, while only 10 in is at stake.

Knitting Until the Yarn Runs Out

The risk at the end is starting a row you cannot finish, or finishing the row with too little left to bind off. Two rules of thumb prevent both.

• A bind-off takes a strand about 4 times the width of the scarf.
• A row of garter stitch takes roughly 3 times the width.

For the 6 in (15 cm) scarf, the bind-off needs about 4 x 6 = 24 in (61 cm). Add 6 in (15 cm) for a tail to weave in, and you must finish your last row with 30 in (76 cm) in hand. One more row costs about 3 x 6 = 18 in (46 cm), so a new row is only safe when at least 30 + 18 = 48 in (122 cm) remains.

In practice, when the ball is down to a few yards, unwind it, measure 48 in (122 cm) from the free end and tie a loose slip knot there. Then:

1. At the start of each row, look for the knot. If it is still ahead of you on the yarn, knit the row, undoing the knot if you reach it.
2. The first time you begin a row and the knot is already behind you, do not knit it. Bind off instead.

For the 5 in (13 cm) scarf the figures are 4 x 5 = 20 in (51 cm) to bind off, 26 in (66 cm) with the tail, and 26 + 15 = 41 in (104 cm) for the knot.

If the Scarf Comes Out Short

Some skeins will not reach scarf length at any sensible width, especially in bulky and super bulky yarn. There are three honest options.

• Make it a loop. A strip of 26-32 in (66-81 cm) seamed at the ends becomes a single-loop infinity scarf. The beginner infinity scarf explains the seam.
• Go up a needle size or two. Larger needles make a looser fabric that covers a little more area per yard and drapes better. The article on needle size for scarves shows the usual ranges for each yarn weight.
• Buy the second skein. If you want a wide, long scarf, check the dye lot number on the label and get a matching skein before you start.

Whichever you choose, a one-skein scarf has only two tails to weave in, and no leftover yarn for fringe, so plan a plain edge from the beginning.
