Marilyn, No I'm SERIOUS. I've used old panty hose or muslin bags to protect crosses in MA. Works like a charm. In OR it is very dry in July so I can use paper bags to cover the crosses. When the seed stalk is ripe but before the seed heads dehisce I cut the stalk and let it complete drying in a paper bag in a cool dry place. Then you just crush the bag gently and all the seeds are retained in the bag. Just decant the contents onto some clean paper and store in glassine envelopes until planting time.
Hair net would let the seeds come right through!
