At Conversations in Cloth this past week, we got the chance to practice Foiling on Fabric.
Katy showed us how to use 007 Bonding Powder to create a starry sky.
Katy also explained how to use stamps (foam, rubber, etc.) to place adhesive glue to fabric. The glue must be completely dry before trying to foil it. Several ladies stamped and foiled satin ribbons for nice effects.
Misty Fuse or other fusible webbing can also be used to apply foil. Each product seems to offer a different effect. In this photo, the Misty Fuse is "lacey" while the Steam-a-Seam is a more solid foil transfer. [Not the best picture, but I think you still get the idea.]
