Clay, you may have just used too concentrated a mix, or maybe wrong kind
of PVA... I never saw the need for it, since you can get unflavored Knox
in any supermarket (& my tests showed Knox as good as any, better than
many gelatins).... but PVA will size paper if it's the right kind (which i
forget now, tho might recognize the term) & right mix.
I saw some test strips on PVA sized paper -- steps were uneven & paler
than similar on gelatin, but for folks who don't want to use gelatin a
possible alternative.
