Bondage Project Hamburg
Workshop program run by Matthias T. J. Grimme and co-trainer Nicole (Rope-Cat), offering evening taster classes, three-day weekend intensives in Japanese-inspired bondage and advanced weekends for small groups of couples. Their teaching puts communication, safety and consent ahead of fixed patterns.
Bondage Project Hamburg is the workshop program of Matthias T. J. Grimme and his partner and co-trainer Nicole, known as Rope-Cat. The team page says Grimme has given workshops on various BDSM topics since about 1996 and has taught mainly rope bondage and Japanese-inspired bondage with Rope-Cat since 2001. It describes him as the author of the SM-Handbuch, the Bondage-Handbuch and the Japan-Bondage-Handbuch, co-editor of the magazine Schlagzeilen, and a visitor to Tokyo who studied with several shibari teachers there. It describes Nicole as having worked with him for many years.
The site describes the approach as putting safety, technique, communication and trust first. Rope is presented as a way to connect and communicate, the structure adapts to the participants, and emotional exchange counts as much as technical skill. Content listed across the formats includes knot technique and ties, anatomy, legal and medical aspects, safety and rope handling.
There are four formats. Evening classes for beginners need no prior knowledge and cover materials, safety and first ties; the schedule calls them “Bondage Basics and Tips for the Bedroom”. A three-day weekend intensive in Japanese bondage runs from Friday to Sunday, from the basics to suspension, for beginners and more experienced pairs. “Bondage II” is a weekend for advanced students with demanding ties and individual focus topics. Private one-to-one workshops are also offered.
Classes are small: home workshops take up to three couples. In November 2026 the schedule listed weekend intensives in Hamburg from 13 to 15 November 2026 and on five weekends between February and July 2027, at €450 per couple, and evening classes on four dates from October 2026 to May 2027, booked with a €30 deposit. The same page lists a Berlin weekend in June 2027 and a bondage weekend at the Dark Secrets venue in Hildesheim in 2027. Workshops in Hamburg take place in St. Pauli, with the exact address sent on registration. The site is in German.
