I recently found PVA glue at an IKEA store here in Southern California.
IKEA is a kit furniture and accessories store chain from Sweden.  The
name on the bottle was Tundra Adhesive.  Made in Sweden.  It was only
about $4 for 500 g.  It is used for gluing down wood flooring.

I was attracted to this glue because of its similarities to PVC-E.  It
dries flexible and seems to have a lot of tack.  I have tried it only
on a few items, but so far I have found it to perform just like PVC-E.

If you don't have an IKEA store near you, you might look for the glue
at a do-it-yourself flooring store.

good luck,
