Generally I have a spreadsheet, and in that spreadsheet I precisely estimate the total stitch count for the project and set it up to automatically calculate completion percentages; I can then weigh the remaining yarn as I go to evaluate and figure out oh, I have used 50% of my yarn to complete 75% of the estimated total, I can make the shawl bigger than originally planned.
But without that system?
Flying blind! Who even knows? Magic! Unicorns are real!
The yarn arrived already caked up and pretty:
|More art than science!|
Turns out: not true. I ran out earlier than budgeted and skipped straight from 86% done to OOPS BINDING OFF NOW:
Jennifer Dassau's tricks for predicting how much yarn one will need for a bindoff row. Two inches left at the end.
Anybody have a middle ground for estimating yardage, some reckoning midway between vanilla computation and a reckless shot in the dark?
