I am looking for Super Coverite covering but it is very hard to find online.
PREFERRABLY: Does anyone know where I can purchase this covering, or an equivalent unfinished pre-adhesived covering?
LAST RESORT: If not, although I really want the iron-on, I will use a doped-on variety but do not want to use silkspan or silk. Silkspan is too weak and looks dull and silk is too hard to get tight.

Any help is appreciated.
