Sofia Rubberstamp Challenge
(Направете си гумен печат у дома и го донесете тук за печат)
Wednesday 17. 12. 2025, 18.00–18.30, Докторска градина
In case of rain we will meet in the gazebo nearby (not wheelchair accessible, but I can come down).
Welcome to my international event project, which aims to popularize handmade rubber stamps among cachers. Therefore, I challenge you to make a simple stamp at home and come and stamp it at this event.
It's pretty simple, just take a scalpel or a sharp pointed knife and an eraser from a stationery store with a flat surface and carve some designs into it. You'd better have potatoes for dinner. The eraser is easier to cut into and doesn't stain my pad with starch. You can carve something with a geocaching theme or just about anything, too. Remember, the print will be mirror reversed and be careful with your fingers. You don't have to be an artist. Any effort is appreciated. Take inspiration from the exhibition at the end of the listing. I'll have a stamp pad with black ink.
There will be a free CWG* (Czech Wood Geocoin) for those who bring their own handmade stamp.
In addition to the stamps, of course, the program for this meeting will be a talk about geocaching and an exchange of trackable items. Spectators are also welcome.
