Modal fabric sits in a curious category: it's made from beech tree pulp, which makes it semi-synthetic, yet it drapes and breathes more like a natural fibre than most polyester blends do. If you've ever reached into a finished garment and thought "this feels like nothing", there's a decent chance modal was involved. For sewists ordering custom digital printed fabric, modal is worth understanding properly before you cut into a new preorder.
What modal actually is
Modal is a type of rayon, produced by dissolving cellulose from beech wood and extruding it into fibres. The manufacturing process gives modal a finer, more uniform structure than standard viscose, which is why it feels so markedly softer to the touch. Lenzing AG, the Austrian company that developed the most widely recognised form of modal under the TENCEL brand, engineered the fibre specifically for softness and wet strength.
That wet strength detail matters in practice. Standard viscose rayon weakens significantly when wet and can distort badly in the wash. Modal holds its structure better, which makes it a more forgiving fabric for garments and accessories that see regular laundering. It's still not as stable as cotton woven, but it's a significant step up from basic rayon.
How modal behaves at the sewing machine
Modal is a knit-adjacent fabric in how it moves, even when it's woven. It drapes low and shifts on the cutting table. Pin generously, or use pattern weights if you have them. A rotary cutter gives cleaner edges than scissors on slippery lengths.
For stitching, a stretch needle (or a ballpoint) works better than a standard sharp, even on woven modal, because the fibres compress and recover rather than snapping cleanly. Use a slightly longer stitch length than you would on quilting cotton: 2.5 mm to 3 mm tends to give a cleaner result without puckering the seam.
Modal does fray. Leave at least 1.5 cm seam allowances and finish your edges promptly, with a serger if you have one. If you don't, a tight zigzag along the raw edge does the job. The fabric doesn't ravel as aggressively as some linens, but leave it unfinished and you'll notice the difference after the first wash.
How modal handles digital prints
This is where modal becomes genuinely exciting for custom fabric buyers. Modal accepts pigment inks with a warmth and depth that flat cotton sometimes can't match, and the softness of the base gives printed designs a more luxurious feel in the finished product. Colours read as slightly more muted and sophisticated on modal than on a bright white cotton base, which suits certain design styles very well.
For bold, saturated prints, cotton bases typically hold digital prints with more contrast. Modal rewards designs that use tonal gradients, watercolour washes, or organic botanical motifs because the slight softness of the base complements that aesthetic. If your design relies on very fine line detail or extreme colour saturation, test on modal before committing to a large preorder.
Washing and care for modal
Modal washes well by most standards, but it does have preferences. Cold to warm water (30°C maximum) keeps the fibres stable and prevents the mild shrinkage that modal can exhibit in its first few washes. A gentle cycle is non-negotiable: the agitation of a full spin cycle can cause pilling along seams and distortion in lightweight modal.
Skip the dryer where possible. Modal dries quickly at room temperature and retains its shape far better when line dried or laid flat. If you do use a dryer, low heat only and remove while still slightly damp. High heat is the fastest way to shorten modal's lifespan.
Ironing is possible on a low setting, with a pressing cloth between the iron and the fabric face. Direct high heat can leave a shine on darker modal pieces that doesn't recover. For printed modal, protecting the design surface is worth the extra step.
What modal works best for
Modal performs best in projects that sit against the skin or need a fluid drape. Loungewear, sleep sets, lightweight tops, and gathered skirts all suit modal well. It's also a strong choice for children's clothing where softness is a priority, though for kids' activewear and anything needing two-way stretch, cotton lycra is generally the more practical base.
For structured projects like bags, home storage items, or anything that needs to hold a shape independently, modal isn't the right call. Its drape works against stiffness. Pair it with a fusible interfacing if you need modal to behave in a more structured way.
Modal vs other soft fabric choices
Sewists often compare modal to bamboo jersey, viscose, and cotton jersey. Each has a different combination of softness, stability, and print quality.
- Modal vs viscose: Modal is more stable when wet, pills less, and tends to hold its shape longer through repeated washing. Viscose drapes more dramatically but is more prone to distortion.
- Modal vs bamboo jersey: Bamboo is marketed on sustainability, but modal from certified beech sources carries comparable environmental credentials. Bamboo jersey is typically a heavier, more textured hand; modal feels finer and lighter.
- Modal vs cotton jersey: Cotton jersey is easier to sew, more stable on the cutting table, and stronger in direct sunlight. Modal wins on softness and drape. For printed garments, the choice usually comes down to the design style and end use.
A word on modal blends
Modal rarely arrives in a pure form at the retail or preorder level. Most modal fabric you'll encounter is blended: modal with cotton (which adds stability and reduces cost), modal with spandex (which adds recovery for activewear), or modal with polyester (which improves durability but reduces breathability). Read the fibre content before ordering. A 90% modal / 10% spandex blend sews very differently from a 50% modal / 50% cotton woven, and the care requirements shift accordingly.
For custom digital printed fabric, the printing base usually specifies the exact blend. Fabric by TrishaMakes prints on specific fabric bases with known fibre contents, so you're never guessing about what you're cutting into when a preorder lands.
