Those look great! Are you using a tying vice? I have been tying flies for my sabiki rigs, and have a few dressed up circle hooks, not sure how well they are going to work yet though, haven't had a chance to get out.
Of course I only have pictures of my junky ones, because I was posting in a what did I do wrong forum. lol
Just so you know, a pool noodle is a cheap way to keep them. I even use them to keep pre-tied rigs on. This is one of my sabiki rig noodles.
