How to Weave Round Circles Without Distorting Their Proportions in Tapestry

Tapestry builds curves from horizontal weft passes and vertical warp threads. That grid produces stepped edges, while the yarn can compress and shift. Rebecca Mezoff explains that small circles are especially demanding because fewer warp threads are available to describe the curve; changing yarn, sett, beat or motif size changes the shaping required.

Separate the outline problem from the spacing problem. A circle can have evenly planned steps yet become narrow when its warps draw together. Conversely, stable warp spacing cannot compensate for closing the top before enough height has been woven. Mezoff documents how insufficient weft brings warps together, affecting both full-width weaving and individual shapes. Bunchy warps near your selvedges? This is why.

A useful working check therefore has three parts: compare the outline with the drawing, inspect the spaces between warps, and measure the packed height. Diagnose which has changed before altering your technique.

Choose a warp-and-weft combination that produces an even, covered surface in a small trial. Sett means the spacing of the warp threads, commonly expressed as ends per inch, or EPI. Mirrix advises pairing finer weft with closer warp spacing and thicker weft with wider spacing, while considering both warp and weft thickness. There is no single sett suitable for every yarn. Tapestry Weaving Basics

Gather contrasting weft colors, small yarn butterflies or bobbins, a tapestry needle, a ruler, paper and your usual beating tool. Prepare the loom according to its own instructions. Before beginning the motif, weave a background section and check that the surface covers the warp without forcing the threads into visibly uneven spacing.

Use the intended circle yarn and background yarn in the trial. Record the sett and yarns so that a successful sample can be repeated. If you change materials for the final piece, treat the earlier sample as a reference rather than an exact shaping pattern.

Draw or trace a full-size circle on paper, then mark its center, horizontal diameter and vertical diameter. This drawing is the tapestry cartoon: a guide positioned behind the warp. Check with a ruler that both diameters match before weaving.

Janna Vallee describes tracing circles directly onto the warp and following the marks. She also stresses testing marking materials for wash-fastness. A removable paper cartoon is a useful alternative when you prefer to keep the guide separate from the yarn. Weaving Circles in Tapestry

For measurement, add quarter-height lines to your paper guide. At each checkpoint, compare the actual woven boundary with the drawing on both sides. Check alignment before reading the measurements: a shifted cartoon can suggest an error that is not present in the weaving.

Avoid transferring a circle onto square graph paper and assuming one square equals one warp thread by one weft pass. Those units need not have equal physical dimensions. If you use a counted chart, first establish their actual spacing in your sample.

For a circle built as a separate shape, begin with the background beneath its lower curve. Vallee recommends weaving the decreasing shapes first: the lower background areas narrow as the circle widens. Build those areas until they would begin widening again, then weave the circle and fill the remaining background. This sequence preserves access to the shed—the opening between warp layers.

Keep separate weft supplies for the circle and the background sections. Follow the cartoon as the lower curve widens, maintain the broad central portion, and then narrow toward the top. At every turn, preserve the alternating over-and-under structure. If a built-up shape obstructs access to a warp, use the tapestry needle to work the required path rather than skipping the thread.

Do not move inward or outward by the same amount at every height. A repeated, uniform step describes a diagonal; a circle requires a changing step pattern. Use the drawing to decide where the boundary moves and where it stays on the same warp.

Woven circles can include surprisingly long straight sections. Mezoff suggests flat tops and bottoms and extended vertical sides, with roughly one-third of the diameter as a starting guide. She explicitly warns that her diagram is not a universal pattern: packing and material choices change the required steps. Weaving circles with hand-dyed tapestry yarn

Use that advice to resist tapering too early. Measure the distance from the bottom to the horizontal centerline before starting the upper half. Then check the upper curve against the lower one at corresponding heights. Let the measured outline guide adjustments instead of copying a fixed number of passes from another weaver’s sample.

Place each weft pass with an arc or several small bubbles of slack before packing it down. The weft needs enough length to travel around the warp threads. Too little draws them together; too much pushes them apart. Vallee’s explanation of bubbling makes warp spacing the practical indicator for choosing the amount. Are your woven 'edges' drawing in?

Watch the circle and adjacent background independently. Where the warps begin crowding, add a little more weft locally. Where they spread, reduce the local bubble. Make small corrections and inspect the next few passes before adjusting again. Apply a consistent beat, which Vallee identifies as essential to keeping woven shapes proportional.

Do not rely only on the outer edges of the tapestry. Mezoff shows that spacing problems can develop inside an otherwise orderly edge. Inspect the exposed warps immediately above the working area as well as the woven surface. Bunchy warps near your selvedges? This is why.

Measure the sample on the loom, then measure it again after removal and the finishing process intended for the final piece. Record width and height separately. Mezoff notes that tapestry packs down and that steam finishing can further change proportions when cotton warp is used. Weaving circles with hand-dyed tapestry yarn

Here is an illustrative calculation, not a measured result or a universal allowance. Suppose a sample measures 3 inches wide and 3 inches high on the loom. After finishing, it measures 3 inches wide and 2.7 inches high. Its retained width is 100%, while its retained height is 90%.

For a desired finished diameter of 3 inches, the corresponding trial dimensions would be:

• Planned width: 3 ÷ 1.00 = 3 inches.
• Planned height: 3 ÷ 0.90 ≈ 3.33 inches.

This suggests testing a slightly taller cartoon with the same materials and technique. The calculation assumes the next sample behaves proportionally; verify that assumption before scaling up. It is useful for a repeatable finishing change, while uneven warp spacing still needs correction during weaving.

Use this diagnostic sequence before adding more rows. The spacing responses follow Vallee’s bubbling guidance; the outline checks apply the measurement method above. Are your woven 'edges' drawing in? I can help!

What you observe	Check first	Next action
Circle becoming narrow	Are its warps crowding together?	Increase local weft allowance gradually.
Circle becoming too wide	Are its warps spreading?	Reduce local weft allowance.
Pointed top or bottom	Does the boundary taper sooner than the cartoon?	Rework the recent steps against the guide.
One side differs from the other	Is the cartoon aligned, and are matching heights being compared?	Correct alignment, then inspect the turn positions.
Circle becomes short after finishing	Did the sample show the same change?	Test a revised vertical allowance.

Keep the first circle as a working record, with its cartoon, materials and before-and-after dimensions. On the next attempt, change the specific variable that caused the distortion. A clear outline, stable warp spacing and measured height give you concrete decisions to make throughout the weave.
