Buying a casket from a funeral home can be damn expensive. The average one costs a little over $2000. And while selling your soul to get one cheaper from Walmart may be tempting, it's not as inexpensive (or as awesome) as making one from a kit sold from Northwoods Casket Company in Beaver Dam, Wisconsin. For $599 and some manual labor, you can make their simple pine box model with your own hands.
This casket kit comes complete with all wooden parts pre-cut. No cutting. No clamping. Kit includes Casket Kit Assembly Instructions, screws, glue, and a piece of sandpaper. The parts are smooth, but sanding is one of those tasks that is never finished. The kit assembles in 1-2 hours. Extra hands make for light work. Keep the blue-stained pine as is, or finish with oil, varnish, paint, or any creative method that inspires you.
Now, if $599 is out of your price range, perhaps you should consider cremation and putting the ashes in this Modest Urn?
All kidding aside, do check out the website for Northwoods Casket Company though. They've got all kinds of interesting things to look at.
