Cross stitch
Cross stitch stitch types: half, quarter, three-quarter and more
Most of a cross stitch pattern is full crosses, but the details live in the partial stitches and the extras on top. Each takes a few minutes to learn once you can spot it on the chart.
Updated October 6, 2026
A full cross fills one square of the chart. Everything else in this guide covers part of a square, sits on top of the crosses, or both. If you can read a chart and make a full cross, each of these takes a few minutes to learn. Most of the trouble comes from recognizing them on the chart, so there's a table for that further down.
The full cross
Two diagonal stitches, one from corner to corner and the second crossing it the other way. The basics page walks through the movements. The one rule that matters for everything below: pick a direction for your top leg and keep it for the whole piece. Either direction is fine. Mixed directions catch the light differently and look patchy.
Half stitch
A half stitch is one leg of a cross: a single diagonal from one corner of the square to the opposite corner. It covers the square more lightly than a full cross, so designers use it for things that should look see-through or faded, like a pale sky, water, a shadow, or a background that shouldn't compete with the main design.
On a chart, a half stitch is usually drawn as a diagonal line across the square, sometimes with a symbol, and the key will say which colors are worked as half stitches. If the line shows a slant, follow it. If the chart only gives a symbol, choose one direction and keep to it. Matching the direction of your top legs is a sensible default, because then the half stitches flow the same way as the crosses around them.
Quarter stitch
A quarter stitch goes from one corner of the square to the center and stops there. On its own it covers very little, so you'll rarely see one alone. Usually it shares a square with a three-quarter stitch in another color.
The center of the square is the awkward part. On evenweave or linen worked over two, there's a hole right there, between the two threads you're stitching over. On Aida there isn't, so you push the needle through the middle of the woven block. Many stitchers manage with their usual tapestry needle; others switch to a sharp embroidery needle just for these stitches.
Three-quarter stitch
A three-quarter stitch is a quarter stitch plus a half stitch. Work the quarter first, from the corner to the center, then lay the half stitch across the square at a right angle to it. The long half stitch sits on top and holds the short leg in place.
On a chart, the three-quarter stitch is usually a color or symbol filling a triangle, half of the square. The long leg runs along the triangle's slanted edge, and the quarter leg goes from the triangle's square corner into the center. That slanted edge is why designers use them: it turns a staircase of full crosses into a smoother diagonal or curve.
Two colors in one square
When two colors meet along a diagonal, each gets part of the square. The usual approach is a three-quarter stitch in the foreground color and a quarter stitch in the background color, so the shape you want people to notice gets the long leg and the crisp edge. When two three-quarter stitches touch, you may find you have to work the quarter after the half to get the needle where it needs to go.
How charts draw partial stitches
Designers don't all mark these the same way. The general chart reading page covers symbols and the key; this table covers the stitches.
| Stitch | What you stitch | How charts usually show it |
|---|---|---|
| Full cross | Two diagonals, corner to corner | Symbol or color filling the whole square |
| Half stitch | One diagonal, corner to corner | Diagonal line across the square, or a symbol noted in the key |
| Quarter stitch | One corner to the center | Small symbol or color in one corner |
| Three-quarter stitch | Quarter plus half | Color or symbol filling a triangle, half the square |
| Backstitch | Straight lines along or across the grid | Solid or dotted line |
| French knot | A knot sitting on the surface | Dot, in one corner of a square or at its center |
Two chart conventions trip people up:
- A triangle on a chart is usually a three-quarter stitch, not a half stitch. It looks like half a square, but the stitch covers three of the four corners.
- A small symbol tucked into one corner can mean either a quarter or a three-quarter stitch, depending on the designer. The World of Cross Stitching's guide to reading patterns, for example, treats a small corner symbol as a three-quarter stitch. When a square holds two small symbols, it's split between two colors.
When in doubt, read the key and any stitch notes before you start. A designer who uses partial stitches nearly always explains their system somewhere.
If you chart your own designs, Craft Studio's editor has half-square and quarter-square partial stitches, along with French knots and backstitch. The half-square fills a triangle, so stitch it as a three-quarter stitch when you work from the printed chart.
Petite stitches
On evenweave and linen, where a normal stitch covers two threads each way, you can fit four tiny full crosses into the same space, each over a single thread. These are petite stitches. Designers use them where a small area needs more detail than the rest of a piece worked over two. They're realistically an evenweave and linen technique: on Aida you'd have to pierce the block in several places for every square. Follow the strand count in the key; stitches over one thread are typically worked with a single strand, where the crosses over two around them take two.
Backstitch
Backstitch is the outline: straight lines that run along the edges of squares or cut across them diagonally, worked after the crosses are finished so it sits on top. It's usually one strand, which keeps lines crisp without crowding the crosses. On charts it shows as a solid or dotted line. The backstitch page covers the stitch itself.
French knots
French knots add dots: eyes, flower centers, snow, the period at the end of a sampler verse. On a chart they're small dots, in one corner of a square or right in the middle.
Mary Corbet, who teaches hand embroidery on her site Needle 'n Thread, gives tips that hold up well for cross stitch:
- Wrap the thread around the needle twice. Don't go past three wraps; more tend to come out loose, snag and look uneven.
- For a bigger knot, use more strands rather than more wraps.
- Don't take the needle back down the same hole it came up through, or the knot can pull through to the back. Go down just beside it.
- Keep the wraps snug on the needle with your other hand, and pull through slowly.
Which order to work them in
Work full crosses and partial stitches together as you go, color by color, so each three-quarter stitch is made while you're already in that area with that thread. Leave backstitch until the crosses it outlines are finished; it's meant to sit on top, and stitching it first means pushing the needle through it later. French knots go in near the end too, once the stitching around them is done, so they don't get flattened or snagged while you work.
Other stitches you may see
Some patterns, especially samplers, add embroidery stitches beyond these. A well-written pattern gives a diagram for each one and lists it separately in the key, along with how many strands to use. If you're unsure whether a stitch belongs on top of the crosses or replaces them, the diagram usually answers it.
If you're starting from a photo, the photo to cross stitch converter reduces the photo to the number of colors you choose and matches each one to the nearest DMC floss. Whatever the source, a chart made only of full crosses shows little stair-steps along diagonals and curves, and that's where a few three-quarter stitches earn their keep.
Frequently asked
- What is the difference between a half stitch and a three-quarter stitch?
- A half stitch is a single diagonal from corner to corner, one leg of a cross. A three-quarter stitch is a half stitch plus a quarter stitch that runs from another corner to the center. On charts, a half stitch is usually a diagonal line and a three-quarter stitch is a filled triangle.
- What does a triangle mean on a cross stitch chart?
- A color or symbol filling a triangle, half of a square, usually means a three-quarter stitch. The long leg runs along the slanted edge of the triangle and the short leg goes from the triangle's square corner to the center. Check the pattern's key, since a few designers use their own conventions.
- How do you do a quarter stitch on Aida?
- Bring the needle up at the corner of the square and take it down through the center of the woven block. Some stitchers use their tapestry needle; others switch to a sharp embroidery needle for these. On evenweave worked over two, the center hole is already there.
- Which way should half stitches slant?
- If the chart draws a diagonal line, follow its slant. If it only shows a symbol, pick one direction and keep it consistent. Matching the direction of your top legs makes the half stitches blend with the crosses around them.
- How many wraps should a French knot have?
- Two wraps is the usual choice, and no more than three, because more tend to come out loose, snag and look uneven. For a bigger knot, use more strands of floss instead. Go down just beside the hole you came up through, not into it.
