3D puff embroidery
3D puff embroidery sews dense satin stitches over a layer of foam, so that part of the design stands up from the fabric. The extra foam is removed after stitching.
3D puff embroidery, also called puff foam embroidery, adds a thin layer of foam under the stitching so part of the design stands up from the fabric. The machine sews heavy satin stitches straight through the foam. The thread holds the foam in a raised, rounded shape, and the foam outside the stitching is removed afterward. Bold lettering and simple shapes such as petals and wings are the usual subjects.
It matters because it gives a texture that thread alone cannot, but it changes how you plan the job. The design has to be digitized for puff foam, with the foam stage marked in the color sequence so you know when to add it. Use a file made for puff foam rather than an ordinary satin design. Some machines include puff designs. Brother's US page for the PR1060W, for example, lists one built-in 3D puff font.
Embroidery Library describes the steps this way. Hoop the fabric with one piece of medium-weight (2.5 oz) cutaway stabilizer. Stitch the design up to the puff stage, following the color change sheet. Place foam about 0.08 to 0.12 in (2 to 3 mm) thick over the area, in a color close to the thread. Stitch the puff stage, then lift away the extra foam and finish the remaining colors. Tweezers pick out stray bits, and the point of small scissors can push foam down into the satin edge.
Choose the needle before you start. Brother says to use a 90/14 for heavyweight fabric or puffy foam, because a 75/11 may bend or break.
Common mistakes: using a design that is not digitized for puff, adding the foam at the wrong stage, choosing foam in a color that clashes with the thread so scraps show, leaving foam bits in the satin edge, and dry cleaning the finished piece, since the chemicals can dissolve the foam. Wash it normally and let it air dry.
Example: Picture a butterfly design with raised wing tips, digitized for 2 to 3 mm foam. The machine stitches the body and outline in normal thread, then stops at the puff color. You lay foam in a matching color over the wing area, and the machine sews the heavy satin over it. You lift away the extra foam, tidy the edges with tweezers, and the machine finishes the last colors. The design is illustrative, not a rule.

Frequently asked questions
Do I need a special machine for 3D puff embroidery?
The sources I read treat it as a stitching technique, not a machine feature. You need a design digitized for puff foam, the foam itself and a suitable needle. Check your manual for needle and thickness limits. Some machines also include puff designs, such as the one 3D puff font listed for the Brother PR1060W.
What needle size should I use for puff foam?
Brother says to use a 90/14 for heavyweight fabric or puffy foam, and warns that a 75/11 may bend or break. Check your own machine manual and the guidance that came with your foam.
Can I wash a piece with puff embroidery?
Embroidery Library says normal laundering is fine, and it suggests air drying. It warns against dry cleaning, because the chemicals can dissolve the foam.
