I've been trying to find a replacement for the Invisible mend cloth I used to use, in the meantime I use off-cuts of shutter curtain material and impact adhesive, I also use this to retape DDS (double darkslides - called film holders in the US). I'm saving my last bit of Invisible mend fabric for more delicate repairs.

Gaffer tape is designed to have a short life, over time the adesives get very sticky then it dries out and the pape breaks down/ I've had to remove it from botched repairs and it always makes a mess. So don't use it .
