Perhaps you haven't heard the story of the loch ness monster.

I tried and tried and tried to knit this. I cannot tell you how hard it was. It's a simple pattern but it was cursed. Well I am going to say the same thing about the sweater. It's making me mental. I knit for hours and then discover that for some reason or another I have to frog. I may try it again later but for now it's just a U.F.O. (unfinished object)

I am going to knit something that I can finish.
