I like to add notes about the irises I send out. Just because I cant be there in person to talk I can still get my voice heard. LOL! So, I keep a supply of little brown bags on hand to write info on or just where I got the iris or how long I have had it or if it is a good increaser, etc., on the brown bag and put the bunch of washed, dried, trimmed, labeled rhizomes in. Then I put the bags in the box with filler as needed. Thin paper bags only and they come in varying sizes.... not at all necessary just something I like to do.
