I just received the pattern today and ran off to my LYS and got some stuff to make this thing happen. Aktion yarns from Lang Yarns, and the circular needles as I didn't have those sizes.
It was hard to decide on yarn choices and I had to extrapolate what the shorts might look like based on the picture of the boxers and their socks and the picture of the socks on the yarn wrapper. At least no one will know, except the partner, if they look ugly!
The next step is to see if I've got gauge! If not, then I'll panic. ;-)
A quick perusal of the pattern shows a few new things for me: wrapping a stitch and edge st.(?). I've worked a short row before in a sock heel turn; hopefully, it's similar. Also, the fact that this is a real garment is new. Hats, scarves, socks and mittens are fairly forgiving items.
So here it goes!
