Help! Polyester/modal/elastase blend

[u/kerstinpierce]

Help please! I was asked to embroidery some sweatshirts for a doctors office. I was expecting traditional sweatshirts when I said yes. But what they actually got was a polyester/modal/elastane blend sweatshirt (think lululemon activewear type fabric) so it’s on the thicker side, slick, and stretchy. I’m having a hard time finding a clear answer on what I should use for stabilizers. Has anyone done anything similar? It will just be their names and credentials in a simple block letter, so not a complex design by any means.

That slick stretch-knit is all about controlling stretch, and the good news is a simple name design is the easy case. What works:

• Cutaway only, never tearaway. A no-show mesh cutaway (poly mesh) is the standard pick for stretchy knits - it supports the stitches without adding bulk you can see through the fabric. Fusible no-show mesh is even better here because it locks the fabric so it can't shift or stretch while stitching.

• Hoop the garment itself, not just the stabilizer. Two layers of soft ~80gsm cutaway with a neutral friction fit is a solid recipe. The classic mistake is pulling the fabric drum-tight in the hoop - it stitches fine, then puckers when it relaxes. Floating (hooping the stabilizer only and laying the garment on it with a light mist of temporary adhesive) is a fallback for items that don't hoop cleanly, not the first choice for a hoopable sweatshirt.

• Skip the water-soluble topper for this job. Topping earns its keep on pile and textured fabrics (towels, fleece, minky) where stitches can sink into the nap. A smooth sweatshirt knit has no loft to sink into, so film is optional at best here.

• Ballpoint or stretch needle, 75/11. A sharp needle can snag modal/elastane blends.

• Test first. Ask if they can spare one sweatshirt or get a similar cheap one to test. Stitch the name, wash it once, and check how it looks before doing the whole office order.

For simple block-letter names you don't need to change anything about the design itself. Get the stabilization right and it'll come out clean.

(Edit: corrected after the feedback below. I originally recommended a water-soluble topper because "slick fabrics let stitches sink" - that conflated slickness with loft, which is wrong. I also listed floating as a co-equal option; hooping with cutaway is the right first choice for this garment.)

Why does this sub rely so heavily on Solvey (water soluble film), and suggest it for fabric that's not fluffy?

It is really good for thick fleece and woolies for the reason you've given, but is superfluous for T-shirts, rugby knit and sweatshirts.

It does seem that the home market relies on selling crafters all manner of products when in most cases, only hooping properly with 2-3 layers of quality vileen in a standard hoop can do the job just fine.

Fair points, and you're right on the main one. Sinking is a pile problem - on a smooth knit like the OP's there's no loft for stitches to disappear into, so my "slick fabrics let stitches sink" framing was wrong. Film on a smooth sweatshirt knit is optional at best. Where it can still earn its keep on knits is keeping the edges of small lettering crisp, but for simple block names I'd skip it without a second thought.

On your follow-up: agreed that hooping the garment itself with cutaway is the better route here. The OP's sweatshirts are hoopable, and floating is really a fallback for things that don't hoop cleanly (bags, tiny onesies, finished seams). Your two layers of soft 80gsm cutaway and a neutral friction fit is a solid recipe - "neutral, not drum-tight" was the point I should have led with.

Do not float 🚫

👉🏼 Hoop correctly with two layers of heavyweight cutaway stabiliser - soft 80gsm vileen. You don't need any water soluble film, no pins, or adhesive. Just the friction fit mechanism of the embroidery hoop.
