Any of you have any experience drying hydrangea blooms?

I'm having trouble figuring out when the blooms are ready to cut. I cut several Annabelle blooms after they turned green again, but only one of them dried green. The rest turned brown. I just went out and cut a few mopheads that have turned green and burgundy to see what happens with them.

All the websites talk about harvesting the blooms after the color has changed and the petals feel papery. I'm assuming I waited too long on the Annebelles that turned brown. Going out and rubbing a bunch of petals to figure out what is papery and what is not is trickier than one would think.

I followed the recommendations that said put the stems in a vase with a little water and leave them while the water evaporates.

All insights and suggestions hardily welcomed!
