In hopes of resolving the low tack mat adhesive holding the conductive fabric in place while cutting a speaker coil we tried the High Tack Adhesive Support Sheet included with the kit.
This product did hold the conductive fabric in place during cutting of a basic rectangular shape, but the fabric trace needed for the circuit was very difficult to remove from the contact paper. Also using the high tack adhesive support sheet caused the remaining conductive fabric to curl rendering it useless for future use.
