If you wish to embroider on very fine and thin
materials sLich as chiffon, organza or silk, we
recommend reinforcing the material with a textile
hardener from PFAFF;
The fabric must be hardened because you cannot
back the material with an embroidery fleece (this
would show through the
thin fabric) Therefore,
repeat the procedure
until
the fabric is strong
e iou g h.
Then fit the fabric tightly into the frame. If you think
that the fabric is still too slack, fit Avalon in the
frame also. The Avalon dissolves in water (available
from your Pfaff dealer). Now you can select your
desired pattern and embroider.
