    I would ask you to include us in your list of vendors of balsa wood. Lonestar Balsa is the resurrection of Lonestar Models after the devastating fire in 2007. We have been supplying balsa to modelers for well over 30 years. We can provide all balsa needs for bridge builders.

    Thanks for your consideration.

    Do you have any idea where I could buy a large set of foam or plastic blocks that would be used to build an arch bridge? I want it to be as large as possible, up to 5 or 6 feet tall even. I haven’t found anything like it on the internet, yet.

    • Garrett Boon - April 7, 2011 at 4:30 am

      Sarah, I don’t fully understand what you need. Are you needing something to bend wood on for the arch bridge? What exactly are the foam or plastic blocks going to be used for?
