1:
Firmly hoop two sheets of Floriani Wet 'n Gone stabilizer for a tight, unstretched and unpuckered embroidery surface.
2:
Embroider a lacy design like "Flower Bouquet Swirl" (II85) directly on the Wet'n Gone stabilizer, and trim the stabilizer around your embroidered design, leaving a small margin.
3:
Using a sponge such as the Spouncer used in this demonstration, dissolve the Wet'n Gone Stabilizer while holding the design on a smooth area of the glass bottle. As it dissolves, the stabilizer deposits adhesive, lightly gluing your embroidery to the bottle -- all in one easy step.
4:
Give the bottle and design approximately an hour of undisturbed drying time, and then fill the bottle with bath salts.
