Fabric: The pattern is designed for medium to heavy weight knit fabrics such as french terry/college with 10-40% stretch. Use the stretch guide in the pattern to evaluate your fabric. For the following pattern pieces we recommend:
JERSEY 10-40% stretch: Neckline strip, welt, pocket bag, shoulder flutter. The zipper facing will also look more neat in jersey, but heavier fabric is fine too.
RIBB (70-80% stretch): Waistband, collar, sleeve cuffs.
The fabric requirement below is an estimation for 150 cm (60”) wide fabrics, not preshrunk. We recommend you to add 20 cm (8”) extra if you’re purchasing new fabric for this project.
Note: the fabric requirements for each individual part of the color block version are not specified, see fabric requirement for bomber jacket with waistband.
1 separating zipper: (if you’re choosing that variant): see length above. Get a zipper that is rather too long than too short. On page 32 we show you how to shorten a zipper. If you’re shortening it you’ll need: pliers, side nippers and two zipper stops.
Snap buttons 10-15 mm in diameter (if you’re choosing that variant): approx. 5-10 buttons depending on size and your preference.
Iron-on interfacing, with or without stretch: To stabilize the fabric if you’re using attaching snap buttons (on the button placket or welt pockets).
Sewing machine needle: Don’t forget to use the right needle for your fabric, for knit fabrics a stretch needle is usually recommended.
Other useful tools: glue marker and/or wonder tape are very useful tools if you’re sewing the zipper.
