Embroidery floss comes as six strands twisted together, but you almost never stitch with all six. How many you use depends on your fabric count and the look you want. Here is a simple chart, then the reasons behind it.
Quick answer
On the most common fabric, 14-count Aida, use 2 strands for cross stitches and 1 strand for backstitch outlines. Bigger squares (lower counts) need more strands; smaller squares (higher counts) need fewer.
Strands chart for every fabric count
| Fabric | Cross stitch | Backstitch | Needle |
|---|---|---|---|
| 6-count Aida | 6 strands (or 2-4 of tapestry wool) | 2-3 | 18-20 |
| 8-count Aida | 4-5 strands | 2 | 20 |
| 11-count Aida | 3 strands | 1-2 | 22 |
| 14-count Aida | 2 strands | 1 | 24 |
| 16-count Aida | 2 strands (1 for a lighter look) | 1 | 26 |
| 18-count Aida | 1-2 strands | 1 | 26 |
| 20-count Aida | 1 strand | 1 | 26-28 |
| 25-count evenweave, over 2 | 2-3 strands | 1 | 24 |
| 28-count evenweave or linen, over 2 | 2 strands | 1 | 24-26 |
| 32-count linen, over 2 | 1-2 strands | 1 | 26 |
| 36-count linen, over 2 | 1 strand | 1 | 26-28 |
“Over 2” means each cross stitch covers two threads of the fabric in each direction, which is how evenweave and linen are usually stitched. So 28-count over 2 gives 14 stitches per inch, the same size as 14-count Aida, and takes the same number of strands.
Why the number of strands matters
The goal is coverage: each X should fill its square so the fabric does not peek through, without being so thick that it crowds the holes. Too few strands and the stitches look thin and patchy; too many and the thread is hard to pull through, the holes stretch, and details blur.
- Want fuller, bolder color? Add one strand (for example 3 on 14-count).
- Want a soft, vintage look? Use one strand fewer and let some fabric show.
- Dark fabric? Coverage matters more, so lean toward the higher number.
Whatever you choose, use the same number of strands for the whole piece (unless the pattern says otherwise), or some areas will look thicker than others.
Backstitch, French knots and blending
- Backstitch outlines are usually 1 strand, so they stay crisp. Use 2 for a bold outline or lettering.
- French knots are usually 2 strands, wrapped once or twice around the needle.
- Blended colors: some patterns ask for one strand each of two colors in the same needle. That still counts as 2 strands.
Try a test square first
Floss brands and fabrics vary a little. Before starting a big project, stitch a small block of 5 × 5 crosses in a corner with your chosen number of strands. If you can see a lot of fabric between the stitches, add a strand; if the holes look stretched, take one away.

Frequently asked questions
How many strands for 14-count cross stitch?
Two strands for cross stitches and one strand for backstitch.
How many strands for 18-count cross stitch?
One or two. Two strands give full coverage; one strand gives a lighter, more delicate look.
How many strands for 11-count cross stitch?
Three strands, so the larger squares are well covered.
Can I use all 6 strands of embroidery floss?
Only on very large fabric such as 6-count Aida. On normal cross stitch fabric six strands are far too thick.
