One of the early ones

This is one of the first patterns I drafted. It is a full course with the same build-along treatment as everything else — but it predates the sizing system and the drafting standards used across the newer catalogue, so expect fewer sizes and a rougher-looking sheet.

It still builds, and it is still one of the most trusted early ones. For the current standard, look at the Yard Jacket or anything released recently.

Fabric

What to make it in

Cotton canvas or duck (10–14 oz)
Reclaimed denim — a few pairs of old jeans, so you have enough to cut around
Waxed cotton for water resistance
Lining (optional): cotton poplin or ripstop nylon

Weights and sourcing are in the materials list that comes with the pattern.

SizesNot layered yet — every size prints together
Seam a/wNot the usual ¼″ — this one predates the standard, so check the sheet
Also insidePanel labels, notches, cutting layout, materials list
LayeringLayered sizing is being added pattern by pattern — Gio and I are working through them in priority order. Every new release has it from the start.

Never printed a pattern before? The print & tiling guide covers it in about twenty minutes.

Before you cut

Measure the 2″ test square first. It's the only thing that goes wrong, and the only thing you can't undo. Print at 100%, from a laptop rather than a phone.

Buy a little more fabric than you need, and run the tricky part once in something cheap before you touch the good stuff.

Never made a pattern before? Start with the free ones — they're the same system, no risk.
