So, now that I've mentioned that I would love it if you could do double fans, all from different clumps... I have to change gears, because you're my friend... It might be easiest for you to dig up everything and just jumble them all together as you split them, wash them, etc. Offering them 25 at a time (or whatever number turns out to fit in a flat rate box) from a big mixed heap should assure everybody of a good assortment of pretties!
If you do try to keep varieties separated as you dig and get them ready, go to Sam's or Costco and get a bunch of those shallow boxes they always have in abundance... they make good trays for things like this.
