Hi Lhillgamer and welcome,
have you got a copy of the ABoK? because the Sheet Bend is #1 ! 
However you can find it (/them) again at #66 and #67, #485, #490, #492… #1431, #1432…
Your second picture (bottom) is a (Right-Hand) Sheet Bend (#1431) (the tails are on the same side = the “true” Sheet Bend), whilst the sequence showed in your first picture (up) is for a Left-Hand Sheet Bend (#1432, tails on opposite sides) that (as Ashley said) “is not so reliable a knot as #1431” (the Right-Hand Sheet Bend).
