Oh come on, that's too easy!
The F bomb. Yep, it's true. That one slips out quite often when itcomes to my sewing especially but sometimes knitting and crocheting and spinning get it too.
And i hit myself over the head with it every once in a while after some crazed usage of my credit card on an online yarn store. DOH!
I also of course thought of "frogging" but, really...that's for others. My wip's just get the F bomb and either get shoved in a drawer or i just decide to FUDGE it (that's another great f word for me ;) ) and leave the error in situ. come on, it's just knitting. no one's going to die from it and i wont get arrested ;)
Have a grreat day :D
