I'm in the same boat as far as bamboo is concerned.
Same with aspen I have to go to Calgary or Lethbridge
As far as base and edges, I've been buying what I can from other members.
Base material comes up from time to time at crown. Just gotta check back often and watch the thickness, as a lot of it is a bit thinner than the step on the edges.

I bought a couple gallons of epoxy from QCM before they sold to Forrest.
MBsnow might still have edges in the commercial section.
I'm pretty sure COsurfer has a bit of stuff for sale in the yard sale section.
Try to get a mailing address in Blaine Wash., probably your closest city in the states, will save you a ton on shipping and brokerage.
Or Point Roberts maybe?
A word of advise, don't get too elaborate with your first pair.
Just a basic wood core and basic materials.
Hope this helps.
Good luck with your building.

You don't even have a legit signature, nothing to reveal who you are and what you do...
Best of luck to you. (uneva)
