The best advice I can give to other DIY brides is to test! everything! I am surprised everyday by the varied ways that things can go wrong. Case in point, our favors:

Each guest will get a little pot of wheat grass to take home with them after the reception. Wheat grass is a convenient choice for favors: it grows quickly, the seed is cheap and easy to obtain and it grows in thick, beautiful green blades. Well, it grows in thick blades most of the time.
Above are three failed wheat grass samples. The leftmost has blades that are too skinny and unkempt and their sheaths are too long. I obtained that particular variety of wheat grass from a local sprout farm, Mung Dynasty, which to their credit is fantastic for everything else.
On the right is a variety of spelt wheat grass from Whole Foods. Clearly, these seeds are meant more for eating because fever than 25% actually germinated. Lastly, in the middle we have grass sprouted from seed that I’ve had in stock for four years. It’s the best candidate, but a great deal of the seed isn’t sprouting. Three strikes.
So, in my current perfectionist fugue I ordered two more varieties of grass seed from wheatgrasskits.com. The first was barley grass and the second was a reliable variety of wheat grass. I’m crossing my fingers.
