DMC Embroidery Floss — What a Skein Is, How Many You Need, and What to Skip
One DMC skein is 8.7 yards of six-strand cotton. Here's how far that actually goes, how to turn a chart's per-colour stitch counts into a shopping list, and why generic floss packs cause more problems than they solve.
DMC stranded cotton is the default thread of counted cross stitch, and "default" is doing real work there — nearly every chart published in the last forty years lists DMC numbers. Understanding what you are buying takes five minutes and saves the two expensive mistakes: buying a colour range you never use, and running out of one colour at 90%.
What one skein is
The product you want is DMC Mouliné Spécial 25, sold in the US as article 117 — so a skein of black is "DMC 117-310".
- 8.7 yards (8 metres) per skein
- Six strands, loosely twisted, meant to be separated
- 100% long-staple Egyptian cotton, double mercerised, made in France
- 500 shades in the current range, including variegated colours
The number on the label — 310, 3347, 816 — is the colour. The 117 is the product line. Retailers write them either way, and both refer to the same skein.
How many strands for your fabric
The whole point of six loosely twisted strands is that you pull out the number you need. Stitching with the skein whole is the most common beginner mistake and produces a lumpy, over-full fabric.
| Fabric | Full cross stitches | Backstitch | | --- | --- | --- | | 11-count Aida | 3 strands | 1–2 | | 14-count Aida | 2 strands | 1 | | 16-count Aida | 2 strands (1 for fine detail) | 1 | | 18-count Aida | 1–2 strands | 1 | | 22-count | 1 strand | 1 |
Separate strands one at a time, then put them back together before threading. Pulling two out as a pair leaves them twisted around each other and the stitch sits badly.
How far a skein goes — and how we got the number
Floss coverage estimates vary wildly across the internet because most of them are quoted without a method. Here is ours, with the arithmetic exposed so you can judge it.
The geometric floor. One skein is 8 m of six-strand, so 48 m of single strand, so 24 m of working thread when you stitch with 2 strands. On 14-count, one Aida square is 25.4 ÷ 14 = 1.81 mm across, so the diagonal of one stitch leg is about 2.57 mm and a full cross is about 5.13 mm of thread on the front. Add roughly the same again for travel on the back and you are at 7.7–10 mm per stitch. That gives 2,400–3,100 stitches per skein in a world with no waste.
The practical number. There is waste: the starting tail, the unusable inch at the end of every length, thread discarded because it went fuzzy, and the extra distance when you jump a gap rather than finish a run. Real consumption lands near half the geometric figure.
So the planning number we use, and the one you will see quoted elsewhere:
Roughly 1,500 full cross stitches per skein, on 14-count, using 2 strands.
Treat it as an order of magnitude, not a measurement. It moves with your tension, whether you loop-start, how tidy your back is, and the count — 18-count uses noticeably less thread per stitch than 11-count.
Turning a chart into a shopping list
A generated chart gives you a stitch count per colour, and that number is what makes floss buying deterministic instead of guesswork. The rule:
skeins = stitches for that colour ÷ 1,500, rounded up, then add one for anything over 3,000
A converted-photo chart from the cross stitch pattern maker has a distribution that surprises people: two or three colours carrying tens of thousands of stitches, and a long tail of colours with under two hundred each. That shape tells you where to spend.
- The long tail: one skein each, no thought required. A colour with 180 stitches will not consume a tenth of a skein.
- The dominant two or three: round up hard, and buy an extra skein of each. Running out of a background at 90% done, with no matching dye lot left, is the most common way a large piece gets abandoned.
Dye lots
DMC colours are colourfast and consistent between production runs, but not perfectly identical. Skeins from different dye lots of the same number can differ enough to show as a visible band in a large solid area. Two rules follow, and they cost nothing: buy all of one colour in one purchase, and buy the dominant colours generously up front — topping up a background six weeks later is exactly where dye lots bite.
For colours used in scattered single stitches, dye lot does not matter; the eye cannot compare two stitches an inch apart.
Full-range set, or per-chart list?
Buy per chart if you stitch one project at a time from published charts. A typical chart uses 15–40 colours; buying those is cheaper than any set and there is no storage problem.
Buy a set if you convert your own photographs. Photo conversion picks colours by what the image contains, not by what you own — one portrait calls for a run of skin tones and greys you would never have bought individually, and the next calls for a different run. A DMC floss set (Amazon) is the sane purchase if you expect to make more than a handful of your own charts.
Prices as of September 2026, US retail: single skeins run roughly $0.50–$0.90 in craft shops, cheaper by the dozen online. Full-range sets of around 500 skeins are typically $180–$350 depending on seller and whether the colours are genuine DMC. The honest arithmetic: a full set pays off somewhere around the fourth or fifth self-converted project, not before.
DMC vs Anchor vs generic packs
Anchor is the other legitimate stranded cotton — also 8.7 yard / 8 m six-strand skeins, around 446 shades, slightly softer in hand, more common in the UK. Genuinely good thread. The catch is that the numbering systems are unrelated: Anchor 403 is not DMC 403. Conversion charts exist and are approximate, because the brands use different dye formulations and some colours have no true twin. Compare actual skeins for anything colour-critical.
Generic multi-colour floss packs — the 100-or-150-skein rainbow boxes sold cheaply online — are where people lose time:
- The numbering is not DMC numbering. Many packs print numbers that look like DMC codes and are not. Some print none at all.
- They are not colour-matched to DMC charts. You will eyeball every substitution, on every chart, forever.
- Consistency varies within the pack — strand thickness and how cleanly the six separate.
Fine for freeform embroidery, friendship bracelets, and children's practice, where nothing references a colour code. A poor fit for counted cross stitch, an activity built entirely on colour codes meaning something. If budget is the constraint, buy genuine DMC for the 15–40 colours your chart needs rather than 150 generic ones you cannot look up.
Storage
Past about thirty colours, loose skeins become unmanageable — they tangle, and the paper bands slip off, destroying the only record of what colour it is.
The standard answer is bobbins: wind each skein onto a card or plastic bobbin, write the DMC number on it, file numerically. Tedious and permanent. The alternative favoured by people with large collections is a floss-away bag system — keep skeins whole in numbered bags and only bobbin the colours in current use.
Either way, the rule that matters is: the number must stay attached to the thread. An unlabelled skein of mid-grey is functionally a skein you do not own. A chart keeper (Amazon) solves the parallel problem for the chart itself.
The five-line version
- DMC Mouliné Spécial 25, article 117 — 8.7 yd / 8 m, six strands, 500 shades.
- 2 strands on 14 and 16-count, 1–2 on 18-count, 1 for backstitch.
- Plan at roughly 1,500 stitches per skein on 14-count with 2 strands; it is an estimate.
- Buy each colour in one go, and over-buy the two or three dominant colours.
- Skip generic packs for counted work — the numbers are the point.
If you have not chosen a chart yet, the pattern maker will give you the per-colour stitch counts to run through step 3, and you can browse finished examples in the pattern gallery.
