Schnittkonstruktion nach Maß: Bluse, Rock, Kleid
Schnittkonstruktion nach Maß: Bluse, Rock, Kleid
## **Workshop Schnittkonstruktion nach Maß: Bluse, Rock, Kleid** In diesem praxisnahen Workshop lernst Du Schritt für Schritt, Grundschnitte nach Maß für verschiedene Arten von Kleidern, Blusen und Röcken zu entwerfen und gezielt anpassen zu können. Dabei beschäftigst Du Dich mit unterschiedlichen Silhouetten, vielfältigen Ausschnitt- und Ärmelvarianten sowie variablen Rocklängen. Der Kurs vermittelt Dir nicht nur die Grundlagen, sondern zeigt Dir auch, wie Du Schnitte individuell an verschiedene Körperformen und -größen anpassen kannst. Auf diese Weise erhältst Du ein umfassendes Verständnis für die kreative und technische Seite der Schnittkonstruktion nach Maß. Darüber hinaus wirst Du anhand ausgewählter Beispiele die erstellten Grundschnitte weiterentwickeln und sie zu konkreten Modellschnitten ausarbeiten. Diese überträgst Du anschließend in Nessel, um Deine Entwürfe sichtbar zu machen und die Passform in der Praxis zu überprüfen. Ein zentrales Hilfsmittel im Kurs ist die speziell skalierte Schablone, auf der die komplexe Geometrie der Körpermaße bereits kodifiziert ist. Mit ihrer Unterstützung lassen sich perfekt passende Grundschnitte schnell, präzise und ohne komplizierte Berechnungen erstellen. Dadurch sparst Du Zeit und gewinnst Sicherheit in der Umsetzung Deiner Ideen. ## **Inhalte des Workshops:** * Maßnehmen und Körpersilhouetten richtig verstehen * Erstellung von Oberteilgrundschnitten mit und ohne Abnäher nach Deinen Maßen * Entwicklung von Kragenschnitten und Varianten * Weiterentwicklung des Oberteilgrundschnittes für zwei Blusen * Erstellung eines Rockgrundschnittes nach individuellen Maßen * Weiterentwicklung des Rockgrundschnittes für zwei unterschiedliche Röcke * Erstellung eines Kleidergrundschnittes nach Deinen Maßen * Weiterentwicklung des Kleidergrundschnittes für ein individuelles Kleid * Fertigung ausgewählter Grundschnitte in Nessel (ohne Saum, Futter etc.) Mit diesem Workshop erhältst Du eine solide Grundlage, um Dein Wissen im Bereich der Schnittgestaltung zu vertiefen und gleichzeitig Deine Kreativität praktisch umzusetzen. **Lineale und das Georechteck zur Methode werden für die Dauer des Kurses gegen eine Pfandgebühr von 75 € zur Verfügung gestellt. Auf Wunsch können sie auch käuflich erworben werden. Die Einzahlung ist bar oder per PayPal möglich.** Anfallende Materialkosten (ca. 15,– € für Nesselstoff, Klebeband + Schnittpapier) werden direkt mit der Dozentin verrechnet, eine Materialliste wird vor Kursbeginn verschickt. Der Kurs richtet sich an alle, die sich mit Mode befassen und den Prozess der Schnittentwicklung kennenlernen oder vertiefen möchten. Du solltest dafür grundlegende Erfahrungen im Nähen haben. **Kursinformation** Anmeldung: https://lette-akademie.de/kurse/schnittkonstruktion-nach-mass/ Termine: Do., 12.

[*Registration form required below*] **Interested in Japanese sword fighting or Japanese culture? Come join a trial and experience the traditional Samurai art at Katori Shintō-ryū in Schöneberg.** **Trial Fee**: **25€**/ session (2hr). Classes every Monday, Wednesday and Friday from 19:00 to 21:00. **!!SIGN UP HERE**: [Katori Shinto-ryū Berlin Sign-up (google.com)](https://docs.google.com/forms/d/e/1FAIpQLSeBt4A13VgnEcgQQ2PDaruthmYMRWineG4KtUCKsuC9KBsCUQ/viewform) Registration is required before your participation so that we can prepare enough training equipment. **Address**: Belziger Str. 25, 10823 Berlin. **No previous experience required!** The classes are in English and German. **Our website**: [Kenjutsu Berlin - Official school of Katori Shinto-ryu in Berlin (katoriberlin.org)](https://katoriberlin.org/) **Katori Shintō-ryū** is one of the oldest Japanese sword fighting traditions (koryū) still practised today and is recognized by the Japanese government as a cultural intangeable asset. The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.

CBusData - Ok I Want to Get Data into Fabric - Now What?
CBusData - Ok I Want to Get Data into Fabric - Now What?
I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.
