The other method is more involved and is based on the thermal shrinking of cloth.

The materials used are thermal shrinking cloth, made of polyvinyl chloride (PVC) and the fabric that will comprise the end result garment, in this example, a thin 100% polyester cloth (Organdie, Voile, Georgette, etc.) Also necessary is a warm waster-soluble filament yarn: #SS110d/1x3 Soluron (Fig. 6) that melts at 104 degrees Fahrenheit or higher temperature.

A thermal treatment machine such as a flat type steam-pressing machine (Fig. 7) is used for the heat treatment at 248 degrees Fahrenheit to 392 degrees Fahrenheit.
First the thermal shrinking cloth is laid on the embroidery machine (Fig. 8).

Then the polyester cloth is layered on top. (Fig. 9) The embroidery begins using the Soloron warm water-soluble filament yarn for the under bobbin thread.

After the design is complete, the embroidered fabric is removed from the machine and laid on the flat steam pressing machine and heat is applied (Fig. 10).

The warm water-soluble under thread is dissolved in water and the thermal shrinking cloth is removed (Fig. 11). The resultant shrinkage percentage is about 40% in both the X and Y axis's. Please note the before and after shots (Figs. 12 and 13).

Other applications for Shrink Embroidery includes partial shrink designs combined with flat embroidery for pleats, tucks, smocking, etc. Printing can also be a part of shrink through its application after thermal treatment and before dissolving the under thread.
The result is a brindled printing with unique coloration on concave and convex shapes.
It is also applicable even after applique or taping embroidery.
