--- title: "Pillow Cover Studio: Throw, Lumbar & Bolster Covers in 3D" url: "https://cushionguide.com/studio/pillow-cover-studio/" --- *Style throw, lumbar and bolster pillow covers in 3D: 16 to 20 in squares, 12 x 20 and 14 x 36 in lumbars, knife, piped or flanged edges and a full cut list.* The Studio · 3D builder # Pillow cover studio: see the color sit down before you do My friends, choose a size, an edge and a cloth, and watch the pillow settle into a sofa corner in the light of your screen — then take the cut list, not the screen, to your maker. ## The quick answer Pick a size — 16, 18 or 20 in square throws, a 12 × 20 or 14 × 36 in lumbar, or an 8 × 20 in bolster — then the edge: knife, piped or flanged. Choose a hidden zipper or an envelope back, the fabric and the fullness. The studio shows the pillow on a sofa and lists every cut piece, the piping length and the fabric to buy. The 3D view could not start on this device (WebGL is switched off or blocked). Every control still updates the plan drawing and the cutting ticket below, and the PNG button saves the plan. Threading the needle — loading the 3D workbench… Still loading on a slow connection. The plan and the cutting ticket already work. Drag to turn, pinch or scroll to zoom.

Here are some of them, with the workshop’s answers. ## How to use the builder ## Bolsters made entirely in the piping stripe A buyer ordered two bench cushions in a deep red with black-and-white striped piping, and two long bolsters, about 7 by 65 in and 7 by 47 in. Then came the good idea: make the bolsters entirely in the stripe. The red speaks, the stripe answers, and the two never argue. Try it here: choose the bolster, the striped cotton and a fine scale, and put the pillow beside a plain one. Let one color speak and the others listen. Choose the piping color by daylight, beside the sofa — never from the screen alone. ## Made from tickets like this one Slate blue velvet with mustard piping gives a Hemnes daybed a relaxed boho finish. Rattan, palms and a vintage rug build on the warm trim. Self-piping in each cushion's own color: the edge stays sharp while the palette stays soft. The piped end of a violet velvet bolster, shown close so you can see the soft pile and how the seam sits on a white daybed. ## Questions about the builder ### What size insert goes in a flanged cover? The insert fills the stuffed body only, so a 20 × 20 in cover with a 2 in flange needs a 16 × 16 in insert. The ticket shows the body size whenever you choose a flange. ### Knife edge or piping on a velvet pillow? Velvet already catches the light on its pile. Self piping gives it a crisp line without a second color; a contrast cord turns the edge into a drawing. Both are sewn the same way. ### Which way should stripes run on a long lumbar? Stripes running up and down repeat many times across a 36 in lumbar and feel lively; stripes running along the length stretch it. Tell your maker which you want — it changes how the panels are cut. ### Does the studio work without WebGL? Partly. Without WebGL the 3D pillow cannot be drawn, but every control still updates the front-view drawing and the cut list, and the PNG button saves that drawing to send with your order. ## Keep measuring - [The Pattern RoomHow to measure a window seat cushion when the walls aren't square](https://cushionguide.com/guides/how-to-measure-window-seat-cushion/) - [The Pattern RoomDown-wrapped or all-foam?
