New brothread Embroidery Puffy Foam 3mm Sheets — 6-Pack Green, washable mid-thickness for raised 3D lettering

New brothread 6PCS Embroidery Puffy Foam 3MM in green is a pack of six 9"×12" sheets designed to lift stitched designs into clean, consistent three-dimensional embroidery effects.

This set supplies mid-thickness foam ideal for producing raised embroidery on hats, jackets, bags and heavy fabrics. Each sheet is colour-matched to common thread tones so the foam remains discreet if a stitch trims away. The sheets are washable, machine-stable and cut easily to size, giving hobbyists and professional embroiderers a reliable material for bold, textured logos and lettering.

How does this foam create a 3D effect?

The foam sits beneath the top embroidery layer; when stitches cover the foam, they compress it and produce a pronounced raised look. After stitching you remove excess foam and lightly heat-shrink what remains so the design appears crisp and rounded.

• 3mm thickness balances height and stitch coverage for smooth contours.
• Place under stitches; trim away exposed edges after embroidery.
• Use a heat gun or steam iron briefly to settle and shrink the foam within the stitches.

Which fabrics and projects work best with 3mm puff foam?

This 3mm foam performs best on medium to heavyweight materials that support raised embroidery without sagging. It’s great for caps, denim, canvas tote bags, felt crafts and nylon outerwear — and you can layer sheets for extra height.

• Recommended on caps and structured hats for classic puff lettering.
• Use on jackets, bags and thick garments like denim or canvas.
• Stack two sheets of 3mm foam for taller 3D effects where needed.

What are the practical care and machine tips?

The foam is water-resistant and made to withstand regular embroidery machines and home laundering when cared for properly. Avoid dry cleaning and don’t over-dry after using heat; follow best-practice machine settings and needle choices for clean results.

• Run machine at a moderate speed (around 400 stitches/min) to avoid foam distortion.
• Match foam colour to thread and use a bobbin colour close to your top thread.
• Choose a larger needle with a shorter shank and longer blade for thick fabrics.

How do I get the neatest finish and longest foam life?

Colour-match foam to your top thread so any small exposed areas blend naturally. After embroidering, trim excess foam carefully and use short, controlled heat to shrink the foam within the stitches; minimal washing extends durability.

• Trim visible foam immediately after stitching for crisp edges.
• Shrink foam with a hair dryer or heat gun; avoid over-drying or high heat.
• Wash only when necessary and avoid dry cleaning to preserve foam shape.

Who is this for: Creators, small embroidery shops and hobbyists who want a reliable, mid-thickness foam for 3D lettering and logos. It’s suited to anyone working on caps, heavy textiles or decorative patches who needs colour-matched sheets that cut cleanly and hold up to machine stitching and normal washing when cared for correctly.
