I recently got from 
some Japanese tenkara hooks from Tenkarabum that feature no hook eye; instead you attach a length of cord, line or silk braid to the hook to create a loop so that you can attach your tippet. Intrigued by the concept and some pictures of really cool flies I found on 
Japanese sites, I decided to give it a try and tie some.
The below is sort of a "how-to" - or at least how I approached the tying process. As always, excuse the somewhat bad quality of the pictures, I am working with a simple point and shoot camera.
|  | 
| The Hooks - Gamakatsu Amago and Owner Yamame | 
|  | 
| The Loop - I am using some white fly line backing that I had laying around | 
|  | 
| instead of just using white, I thought I would have fun with colors using a Sharpie | 
|  | 
| Gamakatsu Amago in size 7.5 | 
|  | 
| first I tie a white base which will give the fly later some translucency when wet | 
|  | 
| next tie in the braid on one side of the hook... | 
|  | 
| ...then tie down on the far side to create a loop | 
|  | 
| trim one tag short, the other longer, this will help creating a tapered body | 
|  | 
| tapered under body | 
|  | 
| now tie in Ultra Thread, silk or similar | 
|  | 
| select a feather, I am using Grouse | 
|  | 
| get rid of the fluff | 
|  | 
| tie the feather in, I typically do that on top of the hook and tip forward | 
|  | 
| trim tip | 
|  | 
| wind hackle, secure hackle stem with thread | 
|  | 
| tie-off thread, fly is finished | 
|  |

|  | 
| voila | 
|  | 
| a hand-full of some eyeless sakasa kebaris | 
Have fund and thanks for stopping by.
