Keep, a small bowl of eggwash or if vegan, tap water will do, and a small towel handy, for Won Ton, I usually roll on a cutting board. Take the pack and roll to separate sheets, handle with dry hands and keep covered with damp papertowel during use to keep moist. Depending on how much you plan to use, you could count the sheets out.
With the round rice papers, have all your veggie cut, dip the rounds into tap water to soften, drain lay ou,t 2/3the way down and lay ingredients, in groups, horizontally the veg or whatev.
Roll over veg upwards(like a blunt) then fold in the sides, to the ends of the veg, roll all the way up, lil bit of water at the top if necessary and allow to air "dry", translucent and colorful, ready to dip, in ponzu or your fav dip...
