I did a google search and came up with something from Crochetville's old posts. It is of Scottish ancestry and has something to do with being just a term for crochet. A word the Scottish people used in regard to crochet/knitting. Hopes that helps.
A crafter in SC is looking for patterns for cleeking. I sent a note(by snail mail) to her early last week but have not heard back from her yet. By any chance is your astrological sign Scorpio? Julianne
