Common questions

What is a division?

Before any stitching, a temari is marked with guide threads. A simple division (S3 to S32) has 3 to 32 lines from pole to pole and the equator. The combination divisions add more great circles: C8 makes 6 eight-way centres with squares and triangles between them, C10 makes 12 ten-way centres with pentagons and triangles. Every layer you add follows the division's symmetry by itself.

Which stitches can I use?

Obi bands, kiku (uwagake or shitagake), chidori zigzags, masu shapes (squares, triangles and pentagons, woven with their neighbours if you like), stars and spirals. Each layer has its own colour bands, rounds and placement. Chidori, masu, stars and spirals need Dotterel Unlock.

What are the measuring strips?

Paper strips that give every distance you need to mark the division on your ball: pole to pole, the equator with its marks, and for C8 and C10 the distances between centres. They are worked out from the ball's circumference you set, and printed at true size in the pattern PDF, cut into pieces with glue tabs when a strip is longer than the paper.

How do I print at true size?

In Export choose Pattern PDF, pick A4 or Letter, and save it. Print at 100 % or “Actual size”, not “Fit to page”, then measure the 100 mm check line with a ruler before you cut the strips. The pattern PDF needs Dotterel Unlock.

How is the thread estimated?

Dotterel adds up the length of every round of every layer on a ball of your size, per colour, and adds 15 % for knots, starts and finishing. It is an estimate: tension, thread thickness and how you travel between rounds change it, so buy a little more.

How does Make mode work?

Make mode lists every step, from wrapping the ball and pinning the poles to each layer and each colour. The ball shows the current step bright, earlier ones faded and later ones hidden. On Android phones the volume keys turn the steps, and the screen stays on. Dotterel remembers the step you reached for each design. Make mode needs Dotterel Unlock.

What is included in the free version, and what does Dotterel Unlock add?

Free: simple divisions up to 12 sections, obi and kiku layers, the 3D view, picture export, the picture card and three saved designs. Dotterel Unlock is a single purchase (USD 9.99, or your local price) and adds C8 and C10 and divisions up to 32, chidori, masu, star and spiral layers, Make mode, the pattern PDF with measuring strips, the turntable video and unlimited designs. There is no subscription.

How do I restore my purchase on Mac?

Open Settings (⌘,) ▸ Dotterel Unlock, or click any padlocked item, and choose Restore Purchase while signed in with the Apple Account that made the purchase.

How do I restore my purchase on Android?

Open Settings ▸ Dotterel Unlock, or tap any padlocked item, and choose Restore Purchase while signed in to the Google account that made the purchase in Google Play.

Do my designs sync between devices?

No. Dotterel keeps your designs on the device, in the app’s own library. Export a design file and open it with Import… on another device. There is no account and no network access.

Something looks wrong with a design.

Please email us what you did, the division and ball size, and a screenshot if you can. The Email the developer button in Settings ▸ About starts a message that includes the app version and never your designs.
