I call it a kerchief because I like the word kerchief better than bandanna. So sue me!
I got the pattern at Crochet n' More: Dog Bandanna Collar Cover
It slips over the collar...no need to tie, and no need for a clasp! Cool! And Loki looks awfully handsome wearing his new doggy accessory...if I do say so myself.
I made another one, using the Tapestry Crochet Technique. I'll post that one later...I don't want to spoil you guys with too many cool posts in a row.
