Your program must handle each of these sections dynamically. A modular design is best. Suggested layers: Crochet Pattern Program
| Component | Description | Example | |-----------|-------------|---------| | | Name, designer, difficulty, yarn, hook, gauge | Gauge: 16 sc x 20 rows = 4" | | Sizes | Small, medium, large with stitch counts | S (M, L): 60 (72, 84) sts | | Abbreviations key | US or UK terms | sc = single crochet | | Special stitches | Bobble, cluster, puff | Bobble: (yo, insert, pull up loop) 3x, yo pull through all | | Instructions | Rows or rounds with repeats | Row 3: [sc 2, inc] 6 times (24) | | Finishing | Seaming, blocking, edging | Fasten off, weave ends | Support multiple formats for different users: | Shape

| Shape | Construction | Math required | |-------|--------------|----------------| | Rectangle | Rows back and forth | length = rows × row_gauge_height | | Tube (in the round) | Continuous spiral or joined rounds | circumference = sts × stitch_width | | Circle | Rounds with regular increases | increase_rounds: sts += increment | | Triangle | Decrease at edges or center | slope = rate of decrease per row | | Sphere | Increase to max circumference then decrease | symmetric inc/dec rounds |
For amigurumi, provide a sphere/ellipsoid generator that outputs rounds with precise inc/dec counts. Implement a gauge converter . User provides gauge (e.g., 16 sts = 4") and desired size (e.g., 20" wide). Formula: stitches_needed = (desired_width_inches / 4) * gauge_stitches_per_4in
