UltraSolvy: This thick, translucent material is sewable and compatible with laser cutting. It is made from polyvinyl alcohol (PVA) and dissolves in water.
Sticky Fabri-Solvy: This water-soluble sticky PVA sheet has the texture of a paper towel (but is stronger) and can also be laser cut. Peel off its backing to attach thin parts for aligned embroidery.
Water-soluble topping: This thin, clear, textured material is sold to prevent embroidery from sinking into fluffy fabrics like towels. Sprayed with adhesive, it can trap parts in a sandwich for embroidery, while still letting you see through to the alignment marks.
PVA glue: Fibers can be coated with this water-soluble glue by pulling them through a tube with the glue in it. This coating can make it easier to attach low surface energy fibers like silicones to the Sticky Fabri-Solvy and other adhesive surfaces.
Wash-A-Way thread: A PVA fiber that can be sewn as needle or bobbin thread. It can hold your fiber in place temporarily during polymer casting.
StretchMagic: This stretchy urethane fiber can be used as a waveguide for red and infrared light.
