Answer: I can't. So here we go again.
I have started to pack, so I pulled out my one semi-fashionable handbag which I had carried last year to look the NYC part... and discovered the Fix-a-Stitch set I had purchased last year! I had completely forgotten about it.
The Fix-A-Stitch tool is a clever little plastic gizmo in several sizes, better than a crochet hook for repairing certain stitches because, unlike using a crochet hook, you don't have to drop your stitch and pick it up from the other side if you are switching between a knit and purl stitch. You just slide the stitch down to the hook at the other end, and you are in business. The videos on the website do a much better job of explaining.
Best part of all: it is made in the USA. Also, it's an awesome, impossible-to-lose (well, almost impossible) shade of pink.
The discovery was just in time, because I found a glaring error on the front button band of my Downton Abbey knit. Fellow Downton Abbey fans know that this past week's episode was particularly distracting on two counts: (1) the amazing house party costumes, and (2) the horrendously awful plot twist. So it's no surprise that I messed up something as obvious as a garter stitch band. I am going to have to take a closer look at the lace panels to make sure there are no errors lurking there as well.
A few minutes with the fix-a-stitch, dropping each stitch down and weaving it back up properly, and the problem was corrected. Hopefully the vendor will be at VKL again this year. I am going to see if she has the laceweight one as well, because I am already regretting not picking it up now that I remember how useful a tool it can be.
