Difficulty: Advanced
The Viper Blazer sewing pattern is a beginner-friendly introduction to tailoring, offering a sleek, 1970s-inspired silhouette. Cropped slightly shorter than a traditional blazer, it features an extended lapel and the option to make it double-breasted for a bold statement or single-breasted for a more classic look. Designed as a versatile base, this pattern can be customized for length, lapel style, and fit, making it perfect for sewists eager to create a tailored jacket with a vintage twist. Ideal for anyone wanting to master the art of blazer-making while crafting a wardrobe staple with personality.

Printing
For the A4/ US letter:
The file will be tiled, and is best printed from Adobe Acrobat. Make sure files are printed at actual size. There will be a test square for you to check sizing on the front page. The pages will then be taped together with either the bullseye, or diamond motif depending on which pattern is purchased
For A0 or copy shop files:
The file is meant to be printed on 36" wide paper. some of the older files are copy shop format, meaning its one long roll, and Fedex is a great option for this, although we really enjoy printing any of our large format prints at https://pdfplotting.com . They can handle both the A4, and copy shop formats, and are a great budget friendly resource! There will be a 2" test square to ensure the pages have been printed at the correct size.
