Here are the few things I have done since February, which I have already ripped out. Even with my new policy of only pulling out legitimate mistakes I managed to accomplish almost nothing in 3 months.
This is the third iteration of this sweater. Still too short and misshapen.
Here is the base of an alpaca lace sweater that I already knit up and ripped out 3 times. I was totally winging it, and it took a lot of experimentation to find a suitable lace pattern. This particular version created strange gaps between the lace repeats. Later versions were lacking sufficient positive and negative space.
It was also a little too scalloped at the bottom. There was no real focus on scallops in the pattern, so it mostly just resembled a mistake. So I treated it like one and ripped it out. Since sipping out two more versions, I'm almost done with the current usable one.
