[LargeFormat] Patching bellows pinholes

[philip lambert]

I thought white PVA glue was used to join wood or paper.  White textile glue
in the UK is Copydex which seems rubber based.  I suppose I could experiment
with both.  Anybody who has tried the graphite plus glue idea care to
comment on the best glue?  P Lambert
