VeganMoFo: Bubbie's Potato Salad

AKA THE BEST potato salad.

My family dish today is special because my dad actually found a hand-written version of the recipe from my Bubbie, who is no longer living. Thanks for scanning it for me, Dad!
That may be a little hard to decipher so here's what it says:
"boil Potatoes
juice from sweet mixed pickles
pour over warm potatoes
1 tsp mustard yellow
gently mix up
mustard seeds a few
when cool
chop mix pickles
celery and onion
chopped
mayo + mix
salt + pepper"

As you can see, there aren't exact measurements, and some of these steps can be taken several ways. This is what I came up with in recreating it:
The sweet mixed pickles are really the star ingredient. Soooo yummy! You've gotta try it- and feel free, as I did, to use each ingredient to taste.
