Prep for the weekend

Just in case that you are in the region of Mannheim this weekend and don't know yet to do with your time, I'll be at the Reiss-Engelhorn-Museum on Saturdy and Sunday together with Nobilitas. From 11 to 18 o'clock, you can not only see us at work doing historical crafts but also try your own hand at these things.
Now... it's still February, which is usually not the warmest month of the year. Weather forecasts say it will be warmer towards the weekend, with up to 10° C in Mannheim, but I have nevertheless planned to bring cold-weather-compatible work (also suitable for having others try).

Unfortunately, this cold-weather-compatible work means that I will have to build some stuff for it today. So if you're looking for me... I'll be over there, with the saw and the hammer and the drill.
