How Many Skeins Do I Need for Cross Stitch?

What is in a skein

DMC and Anchor stranded cotton skeins hold 8 meters (315 inches) of six-strand floss. Cross stitch on 14-count usually uses 2 strands, so one skein gives three 8 m lengths of 2-strand thread.

A full cross uses about half an inch of that thread: two diagonals on the front and two short passes on the back. 8 m × 3 is about 945 inches, or 1,890 stitches, and 1,643 after allowing 15% for tails and unpicking.

Skeins per color

• → 4,000 stitches: 4,000 ÷ 1,643 = 2.43 → 3 skeins
• → 2,000 stitches: 1.22 → 2 skeins
• → 500 stitches: 0.30 → 1 skein

Example: a 10,000-stitch design with 8 colors

If the chart does not list stitches per color, estimate each color's share of the design by eye.

That comes to 3 + 1 + 1 + 5 = 10 skeins. The thread itself would fit in about 7 skeins, but each color is bought whole. Buy a spare skein of the background color.

When one skein is not enough of the same dye lot

Stranded cotton is dyed in batches, and batches of the same color number are not identical. The difference is small enough to miss in the shop and large enough to see in a finished piece, as a faint band where one skein ran out and the next began. It shows most in large areas of a single mid-tone, and least in scattered detail.

The rule that follows is simple: any color your estimate says needs two or more skeins should be bought at the same time, from the same shop. DMC prints a lot number on the paper band, so keep the band until the color is finished rather than pulling it off when you wind the bobbin. For a color that is close to the boundary, say 1.8 skeins, round up and buy three rather than two, because coming back for the third months later is the case where the mismatch happens.

If a mismatch does turn up mid-project, do not start the new skein at the edge of a stitched area. Work the two lots alternately across a few rows so the change is gradual, or save the odd skein for detail elsewhere in the piece.

Why a kit contains less thread than this calculation

Kits rarely include whole skeins. They include measured lengths, cut to the design with a working margin, which is why a kit for a 10,000-stitch design weighs a fraction of the eight or nine skeins an estimate asks for. The estimate is not wrong: it is answering a different question, which is how much to buy when floss is sold whole.

The consequence is that kits have almost no margin for error. Unpicking a large area, or losing a length to a knot, can leave you genuinely short of a color that has no spare. If you are working from a kit and you expect to unpick, buy one skein of the dominant color separately before you start. If you are buying everything yourself, you already have a 15% buffer and whole skeins on top of it, and the leftovers become the start of a stash rather than a loss.

Before you buy

• Buy each color from one dye lot

  Shades vary slightly between batches. Buy all skeins of a color at once, especially for backgrounds.

• Check the chart key first

  Many patterns list stitch counts or skeins per color. Use those figures when they are given.

• Adjust for your fabric

  11-count stitches are bigger and usually take 3 strands, so allow about 50% more thread than on 14-count.

• Count backstitch separately

  Outlines are not in the cross stitch count. Most use 1 strand, and one skein covers a lot of backstitch.

The thread calculator works from a total stitch count, and the floss calculator lists skein lengths for other threads.
