Good luck, Puffkin! It's actually better that you're taking a break from trying. It may give some time for the swelling from your previous attempts to go down.
Using the dental floss really works it doesn't have to be the real wide stuff. In the ER we used to use suture thread. I've taken many rings and several other objects that kids have thought to put their fingers into by this method. You do have to wrap it tight and go slow it won't come off all at once.
Well, we tried last night with all the methods above and it didn't budge
My finger was still puffy though from the earlier attempts so we are going to give the swelling a few days to go down before we try again. If we can't get it off by the weekend, I guess we will be going to the jewelery store to get it cut off.
