Enter your fiber blend and today's humidity — get a GO/WAIT/CAUTION verdict, exact drying time estimate, and fiber-specific risk warnings before you commit a $200–500 project.
Live Example
Estimates based on textile research and knitter community data. Always block a swatch first.
Features
Today's humidity + temperature → instant blocking verdict. Never start a blocking session on a 90% humidity day again.
Fiber × weight × item type × humidity = hours to dry. Wool lace shawl vs. superwash sweater vs. alpaca blanket — all different. (Pro)
Mohair felts at 30%+ stretch. Superwash can grow to your knees. Silk weakens wet. Know the risks before you block. (Pro)
Enter current and target dimensions. Get NORMAL / AGGRESSIVE / EXCEEDS FIBER CAPACITY — so you know before you pin. (Pro)
Notification at the optimal flip window so underside airflow prevents uneven drying. Never forget mid-block again. (Pro)
See which day this week has the lowest humidity and shortest estimated drying time for your default fiber. Plan ahead. (Pro)
Track multiple pieces mid-blocking. Progress bar + flip window status for each active WIP. No more "is it dry yet?" guessing.
Per-fiber reference: dry time range, growth %, recommended method, and community-sourced notes for all 10 fiber types. (Pro)

How It Works
Select a single fiber or enter a custom blend with % sliders
Lace shawl or bulky sweater — yarn weight changes drying time significantly
