Learn a poetic form and practice writing one

Teach me a poetic form and guide me through writing my own. Form I want to learn: [e.g. "sonnet", "villanelle", "haiku", "ghazal", "pantoum", "not sure - suggest one"] My level: [new to poetry / write free verse / know some forms] A subject I'd like to write about: [e.g. "my morning walk", "my dog getting old"] Teach it in this order: 1. The rules in plain words: number of lines, rhyme scheme, meter or syllable count, repeated lines, any turn or shift. Show the pattern visually (e.g. A1 b A2). 2. Why poets use this form: what effect the rules create. 3. A short original example you write on a different subject from mine, with notes showing where each rule appears. 4. Common beginner mistakes with this form (e.g. forcing rhymes, padding lines to hit a count). 5. A step-by-step exercise for my subject: start with brainstorming images and words, then the key lines, then fill in the rest. Then ask me to write my attempt and paste it back. When I do, check it against the rules, point out where I bent them (and whether that works), and suggest one improvement. Do not write my poem for me. Only use examples you write yourself; if you mention famous poems in this form, name them for me to look up rather than quoting them.
