I just received this pic from Carol, A Lost Socks Swapper Extraordinaire!
She has been fearlessly tackling the Long socks. I am working on these now too.
Not quite as easy as the little ones if you can't figure out whether or not they are on straight!
There must be a way to center them and align them vertically,I just haven't figured it out yet.
On the bright side, there are only twenty of these blocks, LOL!
