This sheet is a high quality latex rubber, that is used as a membrane when building a Cymatics Sounder.

We offer it only because we had a very difficult time sourcing it for our Sounder, and we wanted to make it easy for others to build theirs.

The sheet size is approximately 11 1/2” x 11”, and is suitable for inserting into a 10” embroidery hoop. It is only available in black.

Please limit your purchase to a maximum of 2. Ordering more than 2 will increase the unit price to $9.99 each. Thank you for understanding.
