G’day Alex, 
Their are a few specialty timber places within 45mins of my home; 3 are recycling repurposing old reclaimed timber. Living Timber in Penrith supported the “Off Cuts Only” challenge giving me a small quantity out of their “offcuts  bin”. I also have scored the odd bits & pieces from a couple of local builders doing Reno’s plus other makers. That’s the beauty of toymaking one only needs smaller pieces of timber. 

Life’s Good, Enjoy Each New Day’s Blessings
