Cindy ~ Stop worrying and plant your irises. And yes, keep a record of what you received, and when and from whom. Maps, charts, lists...etc.
If you have a notebook for this purpose, all the better. Then it will show any additions that you may have made to any original orders. If you lose internet connection, will you have a list of your irises and where they are located?
I think that is what most of us do...not entirely sure...
