my dd and I have collected a handful of conkers today so I just want to check what you do with them? We are going to make a necklace... they are fairly small sized and we've got some beads which she can thread too. I remember dd's yoga teacher sharing one with the kiddies which her son had made.
I've read on some sites to soak the conkers in vinegar. Others suggest baking them for a few mins. One said both. I guess these tips harden them up?
