There is nothing worse than happily weaving along and suddenly realizing that you are about to run out of warp (or weft) before you’ve reached the woven length you need. You call everywhere to order more yarn (you’d pay for Next Hour) but—oh, no!—that yarn no longer exists. A much better MO for your weaving life is to know how much yarn you need before you start weaving and make sure you have that much or more.
