How is a chenille patch built?

A chenille letter or patch is made in layers, and the file has to plan each one:

  1. Felt base. Wilcom notes that the backing for chenille is usually felt, softer than regular embroidery backing. Some patch makers use a single layer of felt; double felt varsity letters sew the chenille onto a top felt color that sits on a larger bottom felt.
  2. Moss fill. The looped moss stitch fills the letter, number or shape and gives the raised texture. See what chenille embroidery is for how the loops are formed.
  3. Chain outline and detail. Chain stitch outlines the moss and sews fine detail. Wilcom explains that chain borders tie in the moss so it does not loosen in washing.
  4. Border and cut. The felt is cut around the design, leaving a felt border, or the edge is finished with satin stitching.
  5. Backing. A sew-on finish, a heat-seal adhesive or a pressure-sensitive adhesive is added last.

Wilcom also describes a method where chenille is backed with a sticky fabric and applied with heat and a press; with that method the moss fill does not need a chain border.

What sizes do chenille letters and patches come in?

Chenille yarn is thick, so size limits are tighter than for flat embroidery. There is no single industry standard; these are the published limits of one patch maker, World Emblem:

RuleWorld Emblem limitWhat it means for your design
Patch size1 x 1 in minimum, 12 x 16 in maximumLarge back designs may need to be split or made as separate letters
Chenille text height30 mm (about 1.2 in) minimumSmaller text should be chain stitch or flat embroidery
Chenille elements3 x 3 mm minimumTiny shapes will not show loop texture
Internal cut-outs10 mm minimumSmall counters, as in a small "A" or "e", fill in
Chenille shareAt least 60% of the patchA design that is mostly detail suits a flat patch better

Varsity letters are sold in set heights. Mount Olympus Awards, for example, offers double felt block letters from 2 to 12 in and at 18 in, measured from chenille edge to chenille edge without the felt. Custom letters are sized to the garment, so give your digitizer the finished height in inches.

Which felt and border styles are used?

  • Felt border: the classic style, with felt left showing around the chenille. World Emblem specifies a felt margin of 4 mm (plus or minus 1 mm) with a 2 mm embroidered outline inside it.
  • Satin border: a satin stitched edge with no excess felt, in standard embroidery thread colors.
  • Felt colors: felt comes in a range of colors, including glitter felt. STAHLS' lists 17 felt options, among them gold and silver glitter.
  • Double felt: the chenille and an optional contrasting border are sewn on a top felt color, which sits on a bottom felt that frames it and is sewn to the garment.

The border style changes the file. A satin border is digitized like the edge of a flat patch, with its own underlay and pull compensation, while a felt border only needs an outline and a cut line. For the flat embroidery around a chenille letter, see satin stitch vs fill stitch.

How are chenille letters and patches applied?

BackingHow it is appliedBest for
Sew-onStitched around the edge onto the garmentVarsity jackets and letterman sweaters, the traditional method
Heat-seal adhesivePressed with a heat press at the maker's settingsCotton, polyester and blends
Pressure-sensitive (peel and stick)Paper removed, pressed firmly on a clean surfaceSmooth hard goods, not garments

Heat settings differ by product, so follow the patch maker's instructions for time, temperature and pressure. STAHLS' lists its heat-applied chenille patches for cotton, polyester and cotton/poly blends, and its pressure-sensitive version for smooth hard goods only, with a 24-hour cure.

What does a chenille letter or patch file need?

The file tells the chenille machine which areas are moss, which are chain, how high the loops sit and in what order everything sews on the felt. To build it, a digitizer needs the artwork, the finished size in inches, the felt colors and layers, the border style and your chenille machine make and model. Send those to our chenille digitizing service for a free quote. If your artwork is a vector file, you can check it first in the free AI and EPS file viewer.

If a patch maker will produce the finished patches, check their size, border and backing rules, like those above, before the artwork is final, so the file and the patch spec agree. For the other techniques in this section, see specialty embroidery, including sequin embroidery.

Frequently asked questions

Chenille yarn is thick, so letters need to be large. World Emblem sets a 30 mm (about 1.2 in) minimum for chenille text; smaller lettering is sewn in chain stitch or flat embroidery.
Both exist. Traditional letterman letters are sewn on; many patch makers also offer a heat-seal backing applied with a heat press, and a peel-and-stick backing for hard goods.
Some makers allow a household iron, but a heat press gives even temperature and pressure. Follow the maker's settings for the patch you have.
Either a margin of felt left around the chenille, usually with a stitched outline inside it, or a satin stitched edge with no felt showing.
Only in chain stitch or flat embroidery. Moss loops cannot hold small detail, so detail-heavy designs suit a flat embroidered patch better.
