I spend this morning ripping out a scarf I had half completed. This pattern was something that looks like blocks that keep shifting positions. I got half way done when the pattern changes and found out the pattern was incorrect. The math calculations were off. Although I spend a lot of time recalculating the math for the error and it seem to be working, I found myself re-writing the pattern. At this point I felt like I should get credit for the patten since I was re-writing it. So finally, I ripped it out and put the yarn to good use on a more reliable pattern. It is so so depressing ripping out something you worked on for a while. I think I will limit my pattern choices to a more reliable source. In my anger I ripped the pattern up and tossed it into the trash. Thanks for listening to my rant. I feel much better!
