On NGS group, we're doing a study of Darlene Olivia McElroy & Sandra Duran Wilson's book "Surface Treatment workshop" This week we're looking at the section Ventilation Tape, previously known to me as foil flashing tape. It is a product similar to aluminum foil, but has adhesive on the back side which is covered by paper. This can be found in the hardware store. This can be used much the same as aluminum foil, but is narrower.
There are some fun suggestions of using this product in the book. Create texture in the ventilation tape (this can be done with an embossing folder, as I did, or over a texture plate or stencil, or drawn on with a pencil).
