Re: [BKARTS] pop up repair question

[Carol Pratt <jcpratt@xxxxxxx>]

Tengujo is a very thin kozo paper, and it is a good choice to use for  
repairing or reinforcing.  It is thin enough that text can be read  
through it.  I have used it a great deal instead of heat-set  
tissues.  As long as you are careful, use paste (not pva), then I  
don't think you will cause any problems.  It will be nearly invisible.

I too have reservations about tyvek, even though archival tyvek is  
available.  Somewhere in the past (possibly this list) there was a  
comment made that tyvek does not have especially good fold endurance,  
but I've not seen any scientific evaluation of it.  Perhaps someone  
else will know?
