The Prince Albert Knot is a classy way to tie a tie. It is very similar to the Christensen, or Cross Knot; however, it builds off a fourinhand base instead of the HalfWindsor. This knot can be very subtle or it can stand out depending on how you adjust and tighten the knot.
In the comments below, let me know if there is a knot you've been having trouble with and I'll put together a video for it.
