It is just one weekend per year, but worth visiting. Well, when you find it - it is a bit hard to get there - I think they decided to built some wrong things into the GPS, coz they have to keep the visitors in a managable number - and it was still very well attended. You will see a lot of handmade things and craftmanship. You can buy great stuff and they sell local mulled wine and specialities for fair prices. The food is mostly provieded by local groups. I had a fresh baked pretzel with cheese and a mulled wine and I took a bottle of local white wine home for hubby who did not come with me - he preferred to cycle 4 hours in a gym.
I saw a lot of good things, but hey, I had to behave myself, so I just bought some handprinted cards and a new teapot (you can see it on the second pic) I am using allready at this moment while I write here.
