Abbreviation query

hi, my crochet pattern calls for me to “1tr, df” do you know what that means?
Also in knitting what is the difference between "wool forward (w.f.) " and "wool front ( w.ft.)


Wool forward and wool front would be the same. Not sure what ‘df’ means.

“1 tr” means 1 triple crochet stitch, sometimes also called 1 treble crochet stitch.

I’ve looked in two lists of abbreviations, including the one in Donna Kooler’s [I]Encyclopedia of Crochet[/I], and neither shows “df.” I don’t remember ever seeing it. Is there any kind of context for it?


You know, it could be a typo of some kind… maybe ‘wf’?
