Recommendations for online vendors of laser cutting materials?
* Wood: basswood sheets, birch (or similar sturdy) plywood, etc
* Leather (vegetable tanned)
* Paper: undetermined cardboard and/or cardstock
What companies are out there that would have a variety of these materials at good prices? (For comparison, we have been mostly leaning on the local Michaels - probably one of the most expensive options per-piece.)
