Someone suggested exterior wood glue, so I'm trying that now. I like $8 a quart better than over $40 a litre (with shipping). It's yellow in the bottle, but has dried pretty close to clear.
I covered a pint glass with cling wrap and covered it with strips of fabric thoroughly saturated with Titebond II.
Removed the glass and cling wrap after 24 hours. Here it is after 4 days, pretty dry and hard. I'm moving outside to test for sun and rain. Then I'll stick it in the freezer...
I got some terra cotta colored Powertex from Crafter's Cafe and will try that next. Powertex also comes in bronze, clear, and charcoal colors.
Awww! Isn't Biscuit pretty in the flowers?
