Lay out a corn husk. This is much easier using the larger ones.
Spread a thin layer of Masa out. We use just enough to coat the husk. If you want a thicker doughy Tamale just use more. Only spread the Masa about 2/3rds of the way down the husk, starting from the wide end. This is done because the bottom of the husk gets folded over later on.
If you only have smaller husks fear not. Just "glue" them together. Lay out one small husk and coat it with Masa as described above. Place the second husk on top with about a half inch or so overlap. Now just coat the second small husk.
