How much thread do I need? Estimating skeins for cross stitch

What is in a skein

A skein of six-strand cotton is 8 metres long, from DMC and Anchor alike (DMC labels it 8.7 yards). The six strands separate, so you choose how many to stitch with. Split into single strands, one skein holds 48 metres of thread; most cross stitch on 14-count uses two strands at a time, giving 24 metres of working thread.

Stitches per skein, by count and strands

How far a skein goes depends on how big each stitch is (the fabric count) and how many strands you use. Each full cross is two diagonals plus the travel across the back to the next stitch, plus thread lost at the start and end of each length.

The pattern is simple: doubling the strands halves the stitches per skein, and a finer count stretches every skein further because each stitch is physically smaller.

Turning a pattern into a shopping list

1. Find the stitches per colour. Every CraftPatterns pattern lists them in the key; for other patterns, the key or a stitch count tool will.
2. Divide by the stitches per skein for your fabric and strands from the table above.
3. Round up to whole skeins.
4. Add one for any colour above about 3,000 stitches, and for any colour that is badly scattered (below).

Here is a real example from our library, calculated by the same code that writes the pattern pages:

Notice that every colour needs a whole skein even though the design is under 700 stitches. On small designs, the number of colours decides the cost, not the number of stitches. If you are choosing between two small patterns, the one with fewer colours is cheaper to make, and leftovers from it go further.

On a large design the arithmetic matters more. Say the background colour of a 200 × 150 photo pattern has 6,500 stitches, worked on 14-count with two strands: 6,500 ÷ 2,191 = 2.97, which rounds up to 3 skeins, and because it is the main colour, buy a fourth so the whole background comes from one dye lot.

The skein calculator does the arithmetic for any count and strand number, and every PDF from the pattern maker prints this list on its cover.

Why some colours run out first

A colour stitched in one solid block uses thread efficiently: each stitch is next to the last, so almost nothing is lost on the back. A colour scattered as single stitches across the design is the opposite. Each lone stitch needs a trip across the back from the previous one, or a fresh start and finish, and both cost thread that a stitch count never shows.

We measured how scattered real pattern colours are across every cross stitch design in our library:

17%lone, against 0% for colours with 500+ stitches

The lesson: the colours with the fewest stitches are usually the most scattered. A colour with 40 stitches spread as highlights can need as much thread as one with several hundred stitches in a block. If a colour is scattered, round its estimate up generously or buy one more skein than the arithmetic says.

To make scattered colours cheaper, stitch them in short passes across a small area, and never carry thread more than about 2 cm (an inch) across the back, especially behind open fabric where it shows through. Further than that, finish and start again. The confetti guide shows how to reduce scatter in a photo pattern before you stitch.

Backstitch and French knots

Backstitch uses far less thread than cross stitch. It is usually worked with one strand, and the thread runs along the line on the front and returns behind it.

Most patterns need a single skein for each backstitch colour, even when the outlines look extensive. The pattern maker adds backstitch and knot thread to the colour’s total, so the shopping list already includes it.

How strand count changes the thread

Changing from two strands to one doubles the stitches per skein, but the fabric shows through more. Only drop a strand on a fine count or when you want a lighter look; stitch a few test crosses first.

Dye lots

Floss is dyed in batches, and even brands known for consistency cannot make every batch perfectly identical; deep reds and very saturated shades are the most prone to small shifts. A change rarely shows in small or scattered areas, but it can show as a faint line across a large background, a sky or a mostly single-colour design.

• Buy all the skeins for a big area at the same time, from the same shop if you can.
• Keep the paper bands on leftovers so you know which skeins match.
• If you must add a later skein, blend it in gradually: alternate old and new lengths over a few rows rather than switching at a straight edge.
• Hand-dyed and variegated threads vary much more; buy extra from the start.

Using what you have

Before you buy, check your stash. The Colours I own list records the threads you have; the pattern makers can then use only those colours, and the shopping list leaves them out. When you substitute another brand, check how close the match is on the colour pages: the DMC to Anchor conversion shows the colour difference for every shade.

Common mistakes

Fabric too

Thread is only half the shopping list. The fabric size calculator tells you how much Aida or evenweave to buy, including a border for framing, and the fabric counts guide explains how count changes both size and thread.
