I decided to get an early start on collecting bits and bobs to start some homemade Christmas decorations so collected some lovely open pine cones yesterday. I took them home and soaked them in hot water for a few minutes to get rid of any undesirables and now they have all closed! I put them in cold water to see if it would reverse it but it didn't. Any ideas of how I get them to open again or will I just have to get some more open ones and not wash these ones? The ones I have are nice but not how I wanted them, I'm sure I'll use them somehow.
If there's no way to sort them the at least this can be a reminder for people to start looking for pine cones now and not leave them too late
