The craft show benefits a good cause, so I said yes, I could shorten the hat. And then I said no, that buttons aren't used much on beanies for men.
Meanwhile, the man talked on his phone.
Our tasks were made more difficult by my customary overzealous weaving in -- finding yarn ends in black, ugh! -- and those many tiny, tight stitches I'd used to attach the buttons.
However, after about 10 tense minutes, we were done. The black hat was now 6 inches deep, edged with a just-completed round of single crochet. And the other hat was free of both buttons and stray threads.
The man was so happy with his hats that he left wearing the urban camo one. He and the hat, if I do say so myself, looked fabulous.
