I google "organza" bags & a bunch of sellers. Not able to recall name of company in California. Their 3"x4" bag was cheap at US$2.10 per 30 bags. Their 4"x6" was $7+.
The 3"x4" bags would fit all Mt Ethna type figs, Salem Dark, Ginoso, RdB, VdB, I258 & LSU variants like Yellow, Red, Improved Celeste, St Gabriel, Champagne & many other smaller figs. However, in terms of ease in use, the 4"x6" stood out. The 4"x6" can easily bag a large fig like Brunswick, Osborne Prolific etc.
I certainly recommend using them during this time of the season. We had 2 days of Wet weather, cold wet mornings for days & hardly any bagged figs ruptured. The unbagged ones certainly did.
