Use cut-away medium stabilizer
Cut-away medium (2.5oz) is essential for knits. The stabilizer stays in to support the stitches through repeated wash. Tear-away on knit looks fine initially but stitches go wonky in 5-10 washes.

How to Embroider on Knit / T-shirts
Knit fabric (t-shirts, polos, sweatshirts, jersey) is the most common embroidery surface — and surprisingly tricky. Stretch, soft hand, and shifting fibers all conspire to ruin embroidery without the right setup. This guide covers t-shirt embroidery done right.
Knit embroidery setup
Switch to ballpoint embroidery needle
Ballpoint needle (size 11-14) is critical for knit. The rounded tip pushes between knit fibers without cutting them, preventing holes in the jersey fabric. Sharp needles damage knits.
Use 40wt polyester thread
40wt polyester (Madeira Polyneon, Isacord) handles knit wash cycles and stretch. 60wt is too thin for typical t-shirt designs. Polyester is more durable than rayon for kid t-shirts that get heavily washed.
Hoop with both pieces of fabric
Hoop the t-shirt AND its stabilizer together — drum-tight, no slack. Some prefer "no-hoop" methods with sticky-back stabilizer, but proper hooping gives cleaner results.
Knit-specific challenges
What goes wrong
Common knit issues:
- Stitches sink: knit absorbs thread into fabric — use water-soluble topping for thick designs
- Distortion after wash: tear-away stabilizer fails — use cut-away
- Holes from sharp needle: visible perforations in knit weave
- Puckering: design too dense for knit ability to absorb
- Hoop marks: drum-tight hoop leaves crease on t-shirt
Best knit projects
What knit works for
Common knit embroidery:
- T-shirt chest logos — 3-4 inch
- Polo shirt embroidery — 3-inch, on the chest
- Sweatshirt back logos — 6-10 inch
- Kids onesies — 2-3 inch with ballpoint
- Pajamas — soft, requires lightweight stabilizer + 60wt thread for softest hand
How to embroider on knit / t-shirts — common questions
What stabilizer for t-shirt embroidery?
Cut-away medium (2.5oz). It stays in to support the stitches through washing — knit fabric does not provide enough structure on its own. Tear-away does not work on knit; stitches go wonky after a few washes.
What needle for t-shirt embroidery?
Ballpoint embroidery needle (size 11-14). The rounded tip pushes between knit fibers without cutting them, preventing holes. Standard sharp needles damage knit fabric.
Can I embroider on stretchy fabric?
Yes — stretchy knit (jersey, t-shirt material) is fine with the right setup: cut-away stabilizer + ballpoint needle. Avoid hooping too tightly; let the stretch breathe slightly. Skip embroidering on heavily-stretched parts (like the ribbed neckband).
Do I need water-soluble topping for t-shirts?
Optional for typical designs. For pile/fleece (sweatshirt fronts) or thick knit, water-soluble topping prevents stitches sinking. For standard t-shirt cotton/poly, no topping needed.
How small can a t-shirt design be?
Comfortably 1-inch with size 11 ballpoint and 60wt thread. Below 1-inch gets unreadable fast (lettering, fine detail blur). Most chest logos are 3-4 inch.
Plan before stitching
Preview density on knit fabric
Knit can pucker with over-dense designs. Preview your design in StitchPilot.ai to confirm density suits knit fabric.
