You do relize that alot of your fly paterns will work you just have to tye them upside down and create a level base in some cases but not all.
examples are wooly buggers , egg sucking leach , rabbit strip leach just put zonker strip over hook barb hair side up to make a tail but leave a long but end so you can palmer wrap it forward .craw patterns ,
clouser minnows , decievers .
Another method is to tye in revers so the material faces over the head of the jig then pull it back so it faces over the bend in the hook make some wraps infront of the material to flair it back and tye off , this will give it bulk with very little material, kinda like you would in the thunder creek style but with out creating a head .
Another option is to take like tinsel, crystal flash or what ever and tye it in the center of the material I do this in two parts top ,then bottom . you will have to finish of by hand . this requires you going over the material to the front it may be esier if you use a piece of scotch tape in reverse sticky side out to hold the material to the front .
You can also make bead chain eyes with heavy mono and two beads just toss the beads on melt the ends of the mono so the beads dont come off and add a bit of supper glue for extra insurance . now just tye those eyes to a hook and finish out your pattern .
If you ice fish wieghted flys work great and one can even cast them with a ultra light ,you may need to add some more split shot a few feet up the line or fish them below a float but it dose work .
Hope you found this post usefull .
