These have been done for a while. I just haven't gotten to the computer to post the picture. :)
I'm now working on Lacey's Christmas Blocks longies, and after that it's a pair out of the same yarn for Niall.
The LTK yarn is a little rough, but it should soften with washing and it doesn't pill much at all.
Here are the finish rugby longies. I think Niall needs a pair of these too.
