Now you see it…
The support that washes away
Some stabilisers are only needed while you stitch. Water-soluble products dissolve when rinsed, leaving your work free of that temporary layer.
For hand stitchery: printable, self-adhesive sheets can carry your design onto fabric. Sulky Stick N Stitch is a useful place to start.
For machine embroidery: OESD AquaMesh is a wash-away backing used for projects such as freestanding lace. The design must be made for that technique.
For towels and fluffy fabrics: Stitch2O topping sits on top to help keep stitches from sinking into the pile. It does not replace the backing underneath.
Use wash-away only when the fabric and threads can be rinsed safely. Test first, follow the removal directions and rinse out the residue thoroughly.
