I also know where you're coming from. I had to rip out almost an entire repeat of a lace pattern on my [SIZE=-1]Hydrangea[/SIZE] shawl (which is currently blocking...yay!) just last week and it took FOREVER. I realized too late that I didn't have enough yarn to do that last repeat. :rollseyes:
For my next lace project, I most certainly will use a lifeline.
Don't worry, you'll get through it! :lol:
