Like Duolingo, but for Crochet: Sculpting 3D Shapes. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Building 3D Forms and Polishing Details and Finishing. It assumes you already know the basics.

Key ideas in Crochet: Sculpting 3D Shapes
- A magic ring uses an adjustable loop that pulls completely closed with its working tail.
- Chain loops leave a fixed central hole where toy stuffing or internal fibers can poke through.
- Cinching the tail tight collapses the foundation ring entirely, leaving zero center opening.
- A flat crochet circle must add the exact starting stitch count to every subsequent round.
- Each new round adds one more plain stitch between increases while the total added stays fixed.
- Starting with 6 single crochets means every new round must increase by exactly 6 stitches.
- Excess stitches crowd the outer circumference and force the fabric to wave into ruffles
- Too few stitches starve the outer edge of circumference, pulling sides upward into a bowl
- Flat crochet requires the circle's circumference to expand in direct proportion to its radius
- A magic ring uses an adjustable loop that pulls completely closed with its working tail
- Crocheting over a single tail leaves it free to slip when the fabric stretches or is washed
- Weaving the tail back and forth with a tapestry needle in opposite directions locks the yarn fibers
- Reversing direction through the dense base of the stitches creates friction that prevents cinched loops popping open
- Slip-stitching and chaining to end each round creates a crooked, visible vertical seam.
- Crocheting in continuous spirals bypasses the slip-stitch seam entirely.
- A running scrap-yarn marker tracks the start of each round without breaking the continuous flow.
