The pricing formula that actually works
Price = (materials × 3) + (time × hourly rate) - then check against the market ceiling. Materials × 3 covers yarn plus finishing (eyes, fill, tags). Time × hourly rate is what your time is genuinely worth ($10–$25/hr is realistic for craft-fair goods). The market ceiling is what similar items sell for at your fair; if your formula price is above the ceiling, cut time - don't cut price.
Why bundle patterns beat one-offs
A single amigurumi that takes 4 hours and sells for $18 nets $6/hr after materials - barely worth it. A tiny amigurumi (from the 30-pattern Farmer's Market bundle) takes 45 minutes and sells for $8 at fairs, which is $9/hr after materials. Small pieces from bundles have the best margin per hour because setup time is amortized across many finished items.
The FileDropStudio inventory strategy
For a $200 craft-fair table, the recommended stock is: 30 small pieces from the fruit/veg or kitchen bundles at $6–8 each (variety draws people to the table), 8–12 gnomes at $18–22 each (impulse-buy price point), and 4 placemat sets at $32/set (the anchor product that pays for the table).
