I have made a significant offering to Thor. As I do not believe in praying to the gods for help, the offering did not ask anything of Thor, but instead I gave my thanks to him for the protection he has offered my family over the last 5 years almost.
The offering was my silver Mjolnir pendant that has been worn around my neck over the years. I ventured on a boat across Lake Windermere and leaned out over the side to throw out my offering to Thor. I did this to offer thanks using something of value to myself, value to Thor and to use the lake as a means of portal between worlds by which to send the gift- emulation of the bog offerings was my goal in the hope that a method once used can be so again.
