Drag a bundle from the heap onto the course. Rotate it — by dragging sideways, with a two-finger twist, the turning wheel, or the ±15° buttons — until the butts point down the slope; it will snap into place within about 12°. Then lay a hazel sway across the course and tap each mark to drive in the iron crooks that hold it.

Devon combed wheat reed dresses down to a smooth, close finish. Norfolk water reed is stiff and long, and is dressed with the leggett into a crisp face. Long straw is made up into yealms and raked down, leaving liggers and spars visible on the surface. Each behaves a little differently under the leggett.

Once every stulch on a roof is laid, lift the ridge roll, cut your chosen edge pattern (scallops, points or plain) with the shearing hook, and spar the liggers in place. You can set a straw finial — a pheasant, fox or owl — from the Ridge & Finial screen, or leave the ridge plain.

No. Stulch has no timer, no score and no way to fail. Take as long as you like on a course; nothing is lost if you stop and come back later.

Only for Spot a thatch, so you can photograph or choose a photo of a real thatched roof you've come across and keep it in your scrapbook. Nothing is uploaded; the photo stays on your device.

No. The whole app, including the lane, the yard and the scrapbook, works offline.
