Well . . . I tried. Here is how far I got:
This one is probably going to be finished in the next couple of days. I have a small amount of sewing left to do, and cuffs still to knit.
I'm pretty sure all the knitting on this sweater is done, I just can't find the instructions, so I'm not entirely sure how it should be constructed (the sleeves seem reasonable enough, but looking at that collar baffles me).
Another one I cannot find the pattern for. This one is particularly sad because my lovely merino wool is now covered in tiny moth holes, so in addition to finding the pattern and sewing the collar and neck zipper, I now have to mend about 10 holes.
I do have the instructions for this one, but stupid me ran out of yarn and will now have to try to order something similar (you can clearly see where I had to switch yarns previously).
