: I'm thinking of using doorskins for the hull :

I am really having a tough time finding the 1/8 (3mm) doorskin material here in Minnesota (St. Paul area). Lot's of the expensive Okume marine grade, but have been searching all over. Menards and Home Depot in this area don't carry it. Closest Lowes is Iowa - and most of the small independent lumber yards don't carry it - or are looking to sell a truckload. In addition to kayak build possibility, I use it extensively in building 4 foot, radio control, multihull sailboats.

Found a source back in Flint, Michigan south of my old home town - but unless you pick it up - freight is a killer! (lumber yard is Michigan Lumber Company - in case there are some builders nearby looking for the stuff). Mahogany, Oak and Birch are stocked.

Would appreciate any names of places in upper midwest that you know of that carry (especially if a chain type store) - or nearby. Thanks in advance.
