Well, I drew up my own design and bought the lumber Saturday. Started working it into shape yesterday and it is slower going than I thought, and now I feel like an idiot because I just saw this on Cabela's:
* Cabela's -- 2x4 Basics® Bench Kit
Just thought I would share this in case anybody else is looking for a starter bench...
Time to go home and start screwing 2x4s together!
